After the second debate, these 5 voters changed their minds. They told us why.

Some life hacks are so good, they should be called "cheat codes." Some cheat codes are so powerful, the people who know them are hesitant to share them.

Everyone has their own favorite tricks and tips. A bunch of them were very kind and shared those secret life hacks on a recent social media post where someone asked, “What’s a life hack so good you almost don’t want to share it?” The thread received over 3500 responses, and we culled the best from them to make our readers’ lives easier.

The advice covers everything from how to win an argument to finding precious metals at your local second-hand store. The life hacks that are “so good” also include ways to prevent potentially aggravating people from getting in your face and the power of learning how to smile.

Here are 19 life hacks that are “so good” people almost didn’t want to share them. (Thankfully, they did.)

1. That's where it goes

"If you look for something and it's not in the first place you look, THAT IS THE PLACE WHERE IT GOES. So when you find it, put it in the first place you looked for it."

2. How to argue (from a lawyer)

"When arguing about something, ask what their interests ('why' they want/don’t want something) are rather than their position. Usually, it’s easier to come to an agreement if you approach a conflict from this angle. Also, conceding a minor point during the argument 'you’re right about x' and 'I don’t disagree with y' tends to lessen the guard of your opposition and thus making it easier to get what you want out of them."

"I just saw something similar to this. If you and another person are arguing over who gets a lemon, you’ll eventually agree to just cut it in half. But if you ask why they want the lemon, you’ll find out one person wants to juice it and one person wants the skin for zest for a recipe, so each party can have 100% of what they want if they just take the time to see the 'why' of the other person."

"Whenever arguing with someone and it's going round and round trying to come up with a compromise, ask 'what does a solution look like to you?' Half the time they got no clue the other half is something you willing to compromise. It has cut down every single argument in my relationship."

3. How to stop a 'Karen' in their tracks

"I work as a receptionist, and my supervisor always asks me how our guests like me even if they are rude to other staff. My trick is when someone is checking in that looks like a typical Karen I always give them a compliment like 'where did you get your nails done? They are so pretty!' It usually works."

"I used be in maintenance for a huge school district. Whenever I was sent to a school where the office staff had a reputation for being cranky complainy crabby pants, I had a whole song and dance I'd run through when I got there. I'd walk into the office with a big smile, acting like the nicest person in the world, just a big dumb puppy who has no idea this is a "crabby admin" school. Then, when the timing is right, I'd let slip the casual comment of 'I really like coming to this school, everyone is so nice!' It's like a magic spell. The grumpuses always tried to live up to my unrealistic view of them, and were always at least reasonable, if not downright pleasant. It always felt like cheating, but really all I was doing was setting an example they wanted to follow."

4. Buy the same socks

"Find a pair of socks you really like. Buy like.... 40 pairs. Throw out your other socks. Now you can just grab any two socks and have a pair. Get a hole in one? Throw it out. You still have tons of others of the same."

5. The 3 hobbies rules

"I was thinking about what I need to be happy, and came to the conclusion that I need 3 hobbies: one creative, one physical, and one social. For social, I do board game nights weekly. This ensures I have something planned for the week to look forward to. For physical, I go to the gym, which, to be honest, I hate and have always hated, so I took up bouldering too. This is a great hobby because it can also be very social, and it's also just fun. And for creative, I dabble in things like drawing, knitting, and other needlework. I also throw in reading here too, because it can make you think and imagine. If you play D&D, this can also combine with social. I've been extremely happy since figuring out for myself. I've always had a list of hobbies I want to try, but this helps me organize them."

6. Learn how to smile

"A genuine looking— and I say looking because it doesn’t need to actually be genuine, smile. It will disarm people making them more comfortable around you, you’ll be more likely to get dates, you’ll be more likely to get jobs, you’ll be more likely to make friends, your dating profile will look better, your wedding pics will look better, hell your social media will look better. Learn how to smile. Look it up on YouTube."

7. The bathroom test

"Being in the restaurant business for over 20 years now, if you go into a restaurant and their bathrooms are dirty, then get out of there. It means most likely, of course, not always, that their kitchen is just as dirty. If the general manager doesn’t care about what the guests can see, he’s definitely not caring about what the guest can’t see and that gets you such a higher chance of food poisoning."

8. Wake up a little earlier

"Getting up consistently to start your day at a reasonable hour - regardless of intent to go anywhere or do anything - really does give you extra time in the week to get sh*t done."

9. How to make someone like you

"To get someone to like you, ask them two questions, then after the second one, validate their response. Repeat. That's it. It's alarmingly effective. Just ask them any question about something they seem like they might want to talk about. hobbies or job or whatever. if you dont know anything about them, ask about the best place they've traveled, or would like to go if they haven't traveled. then, whatever they say, just ask a follow-up question about it. Then whatever they say to that, just say something positive that supports their opinion. it can be as simple as 'that seems really cool' or something more specific that shows you've been listening and agree/support them."

10. Visualize your life

"Ask yourself what your ideal happy life would look like, and then isolate each aspect as an objective to work towards, always breaking down larger goals into smaller doable steps. Makes things seem less daunting and gives you feasable objectives to work towards."

11. Know the goal of the conversation

"Before entering any difficult conversation, conflict, apology, request, etc, you should know what your goal of the conversation for yourself is. What do you want the outcome to be? How do you want this interaction to end? How do you want both parties to be left feeling? Know this first, then practice running both sides in your head a few times. Crucially, this prepares you direct the conversation for the outcome you want, instead of just saying what you really want say. Know your goal, and you’re way more likely to reach it."

12. Thrift store jewelry

"Second-hand shops—check the jewelry because, funnily enough, the volunteers working there probably don't know much about gold. I make a fair good chunk of cash a year going through jewelry at thrift stores."

Social media is overflowing with people eagerly sharing their best thrift store finds.

13. Bake bacon

"Piece of parchment paper over any type of pan. Bam, no mess. People boiling it in skillets on the stove are living in the stone age."

14. How to talk to new people

"When the conversation starts to die or needs a pick me up, ask what the people around you did that day. It sounds really simple, but not a lot of people get asked this question regularly, so it’s likely you’ll get a genuine answer and make the person feel like you’re interested and invested. This is my hack for work events, family you haven’t seen in ages, or a friend of a friend you just met and your mutual friend just left you two alone. I think it’s safe to assume it would be a good icebreaker on a first date as well."

15. Self-control through pain

"The only thing in control of your mind and body is you. Go stand out in the rain and fight the instinct to flee inside. Find your zen. Overcome your base instincts and then figure out how to apply them to the rest of your life. Hunger, anxiety, self-esteem issues, etc, all things to overcome, master, and control."

16. Easy investment

"Invest (a portion of ) every paycheck into an S&P 500 index fund. It’s easy, the fees are incredibly low (nobody seems to understand mutual funds that are not index charge a fee! and if you do it consistently you will end up with money. Proven through depressions, recessions, and large-scale wars. That is all."

17. Know their name

"When a customer service person (finally) answers the phone and says 'my name is [NAME], [something something] how can I help you?' I make a note of their name and say, "Hi [NAME], how's it going/how are you doing?" in a friendly, conversational tone before introducing myself & my issue. Customer service is a soulless job and involves dealing with a lot of belligerent people, so setting the tone and establishing a rapport by mentioning their names makes it a little more personal and tends to lead to better outcomes. Can probably expand this to all interactions, tbh."

18. Cook like a French chef

"For cooking: The idea of ”Mise en place“ it‘s a French phrase that means ”Put in place“ before you start any cooking you set up and put all your ingredients to side: spices, sauces, all your veggies are cut and ready to put in the bowl or pan before you cook. Makes cooking 100% less stressful when you have everything ready and on hand."

19. Hack your phone's autocorrect
