All of them are simple and practical. A few might just change your life.

Arjun Mahadevan's life pro tip Twitter thread
Arjun Mahadevan gave the world a gift when he crowdsourced the best โlife pro tipsโ from nearly 22 million people. He shared the top 20 in a Twitter thread thatโs got over 619,000 views. Mahadevan sourced the tips from the Life Pro Tips subforum on Reddit, which has been running since 2010.
Mahadevan is the CEO of doolaHQ which he calls the โbusiness-in-a-boxโ for LLCs.
Mahadevan labeled his advice โ20 life tips you wish you knew when you were 20,โ but they are helpful for everyone regardless of age. Theyโre useful for anyone who is in a relationship, has a job, or wants to stay sane in an aggravating world.
Many ideas involve reframing how we judge others to see them with more compassion. Mahadevan also has some advice for professionals to prevent them from making embarrassing mistakes or wasting other peopleโs time.
Sometimes the simplest change in behavior or perspective can drastically affect our lives. Here are Arjun Mahadevanโs 20 life tips you wish you knew when you were 20:
1. "If youโre stuck on an annoying call, put your phone on airplane mode instead of just hanging up. The other person will see 'call failed' instead of 'call ended.'"
2. "When you sign up for anything online, put the websiteโs name as your middle name. That way when you receive spam/advert emails, you will know who sold your info."
3. "Always tell a child who is wearing a helmet how cool you think their helmet is. It will encourage them to always wear it in the future."
4. "When you don't have all the facts, try to give people the most generous reason you can for their behavior. Annoyingly slow driver? Maybe it's a mom with a birthday cake in the back. This mindset will gradually make you less reactive and more compassionate."
5. "Do not try to be the man your father would want you to be. Be the man you would like your son to be. It more clearly defines your own convictions, desires, goals and motivates you to be your best."
6. "When a friend is upset, ask them one simple question before saying anything else: 'Do you want to talk about it or do you want to be distracted from it?'"
7. "After a bad breakup, do 10 things that your ex would never do with you. You'll feel better and realize how much of yourself was being held back."
8. "Before you give your child a unique name, try it out first. Use it on food orders, reservations, appointments where applicable, etc. Itโll give you a glimpse of what theyโll deal with when theyโre older and could prevent future issues."
9. "If you need to cancel a hotel reservation but are unable to because of a 24-hour policy, call the company and move your reservation to a later date. Call back within a few days and cancel for no charge."
10. "If you tell someone you need to talk to them, for the love of God give some indication of what you need to talk about, or at least that it's not bad news."
11. "Never send a work email when youโre emotionally compromised. Type it up, save it as a draft, and walk away. Ideally, sleep on it. Youโll make a smarter choice when you're not heated."
12. "Don't just let kids win at games. You can slow it down, you can teach them strategy, but keep it real. Someday, they will beat you fair and square, and it will be a moment they always remember with pride."
13. "When cooking things on aluminum foil, first scrunch the foil up, then lay it loosely flat again out on your baking tray. The juices will stay putโand the food will not stick to the foil half as much, if at all."
14. "If you think of a good idea, write it down. Your brain will try to trick you into thinking you will remember it later, but it's a liar! Therefore: Write it down!"
15. "It takes 4 minutes a day and almost no cost to maintain dental hygiene. It takes a lifetime and a lot of money to correct it. 2-minute brush and mouthwash in the AM, 2-minute brush and floss in the PM."
16. "Donโt wait until you have 'time' to start a fitness program. Because then when you get busy again, youโll stop. The best time to start is actually when youโre busy. Learning how to fit it in when times are tough means youโll stick with it over the long haul."
17. "When using text messages or IMs for business, say everything you need to say in the first message. Donโt just say 'hi' or 'hey' or 'are you there' or 'are you busy.'"
18. "Instead of feeling that you've blown the day and thinking, 'I'll get back on track tomorrow, think of each day as a set of four quarters:
โข Morningโข Middayโข Afternoonโข Evening
If you blow one quarter, you get back on track for the next quarter."
19. "Many problems in marriage are really just problems with being a bad roommate. Learn how to be a good roommate, and it will solve many of the main issues that plague marriages. This includes communicating about something bothering you before you get too angry."
20. "Ask yourself 'what does it matter to me' the next time you find yourself judging someone for their clothing or hobbies. The more you train yourself to not care about the personal preferences of other people, the more relaxed and nicer you become as a person."
