Millennials nearing 40 are sharing their biggest mistakes so everyone can learn from them
Here are 21 of the most powerful responses.

Millennials are now old enough to seriously reflect on life.
It seems like only yesterday a millennial was a college kid that baby boomers chided for being entitled and Gen Xers thought were way too sincere and needed to learn how to take a joke. Today, the oldest millennials, those born around 1980, have hit their 40s and have lived long enough to have some serious regrets.
They also have enough experience to take some pride in decisions that, in hindsight, were the right moves. The good news is that at 40 there is still plenty of time to learn from our successes and failures to set ourselves up for a great second half of life. These lessons are also valuable to the Gen Zers coming up who can avoid the pitfalls of the older generation.
A Reddit user who has since deleted their profile asked millennials nearing 40 “what were your biggest mistakes at this point in life?” and they received more than 2,200 responses. The biggest regrets these millennials have are being flippant about their health and not saving enough money when they were younger.
They also realized that the carefree days of youth are fleeting and impossible to get back. So they should have spent less time working and more time enjoying themselves. Many also lamented that they should have taken their education more seriously in their 20s so they have more opportunities now.
The responses to this thread are bittersweet. It's tough hearing people come to grips with their regrets but the realizations are also opportunities to grow. Hopefully, some younger people will read this thread and take the advice to heart.

"Take care of your fucking back. Lift with your knees. Sure it's rad when you grab a fridge by yourself and lift it in the back of a moving truck unaided, but one day that shit is going to have consequences that won't just magically go away by resting and "taking it easy" for a week." — GuyTallman

"I'm 37. I absolutely could have taken better care of my body, but I'm in relatively good health. I'm starting to realize how important it is to maintain my health. I do also think I drank far too much in my 20 and early 30's. I'm trying to rectify that now, but it's hard. So that I guess." — dartastic

"I'm not sure if people have experienced the same but when I entered my 30s I became convinced I was rapidly running out of time. Rather than using that as motivation I let it paralyze me with indecision because I "couldn't afford to make the wrong choice." Consequently, I'm now 39 and, though I've had great things happen in my 30s, I regret spending so much time worrying and so little time committing to a course of action." — tomwaste

"Work to live, don’t live to work. You have half your working life after you turn 40 but only 20-25 years to really live it up before the responsibilities become heavy and your joints start to ache. Live life. Really LIVE it. Experience as much you can. Every sensation, sight, sound, touch. Be open. Be brave. Live your first few decades in the fast lane. You have the rest of your life to take it easy, when you have no choice." — MrDundee666

"Not recognizing the importance of work/life balance earlier in life. My late teens, all 20's, and early 30's were spent pulling 60-100+hr weeks because I thought it was what was required to succeed. How wrong I was. Others stabbed me in the back and reaped the reward.
1.) Putting work first for too long. Work is my #1 priority during work hours now. After quitting time, I don't think about it (much) anymore. I don't vent to my wife or friends about it anymore either.
2.) Investing more into fast cars than solid long-term investments. Sure, it was fun, but I could have made bookoos more had I put that towards less-fun investments.
3.) Not using PTO and just waiting for the payout. All those years, missed. I'm in my mid 30's and I didn't actually have a real vacation until 3 years ago.
4.) Not realizing that "the good guy" often loses. Just because you're morally justified doesn't mean you're going to win. Just because there's a number to call doesn't mean anyone will actually help you. Just because "law" exists, doesn't mean people follow it, enforce it, or create justice. The world is dog eat dog and cynicism can be healthy in moderate doses." — [Deleted]

"I imagine these are kinda universal:
- Not getting fit and healthy
- Assuming I'd be offered proper guidance on how to achieve my goals
- Assuming higher education would help me achieve my goals
- Spending far too long caring what people think
- Not taking risks that might better my life when I was younger and had nothing to lose
- Staying in relationships too long after they were clearly done." — katapultperson

"Always ask for more pay. Starting, yearly, before leaving, whatever. Get that money." — SensibleReply

"Spending too much time in front of a screen and not enough enjoying life." — BellaPadella

American portion sizes are colossal.
Tax shouldn't be a not-so-fun surprise at the end of your shopping trip.
A trip to the doctor shouldn't break the bank.
This totally isn't weird at all. Right?
It's a choice.
America loves extra sugar in savory foods.

Mom is totally humiliated after her kindergartner tells the teacher what she does for work
She was clearly mortified.
A mom is embarrassed by her child.
One of the great joys and stresses of parenting is that you never know what will come out of your child’s mouth. When you have young, inquisitive kids, they can say really inappropriate things to people without realizing they were being rude or possibly offensive. TikTok influencer Aurora McCausland (@auroramccausland), known for her DIY cleaning tips, recently told a funny story on the platform about how her son believes she makes a living. The problem was that she heard about it from her child's teacher.
Mom is embarrassed by her child
“The other day, I went and picked my five year old up from school and when I get to his classroom his teacher pulls me inside and says, ‘Hey, today he wanted to tell us about what Mommy does for work and said that Mommy makes videos in her bedroom but only when I'm [he’s] not at home,” McCausland recalled.
Given her body language while telling the story, McCausland was clearly mortified after hearing what her child said to his teacher. It makes it look like she may be posting videos to adult sites while her child is at school, which most people wouldn’t want their son’s teacher to know about.
The good news is that another teacher was there to clarify the young boy's comments by adding, “I think she makes TikTok videos.” The uncomfortable situation was a great invitation to chat with her son about what she does for a living. “So I have to have a conversation with my son about how he tells people what I do for work,” she finished her video.
The funny video went viral, earning over 1.7 million views on TikTok, and inspired many people to share the times when their children had funny ways of explaining their careers. The commenters were a great reminder to parents everywhere that if your child says something embarrassing, it's ok, just about everyone has been through it.
Moms share their most embarrassing moments
A lot of parents spoke up in the comments to show McCausland that she's not the only one to feel embarrassed in front of her child's teacher.
"My son told everyone that we were homeless (because we don’t own our home, we rent)," KBR wrote.
"I work in ortho.. my daughter told her teacher I steal people's knees bc she heard me talking to my husband about a knee replacement," Aingeal wrote.
"My son told a teacher we were living in our car over the summer. Camping. We went camping," Kera wrote.
"In kinder, my son thought Red Bull was alcohol and told his teacher I liked to have beer on the way to school," Ashley wrote.
My niece told her teacher her mom and dad work at the wh*re house. They work at the courthouse," Ellis wrote.
"My husband works as a table games dealer at a casino. Kindergartener, 'Daddy's a Dealer!' We now start every school year clearly stating he works at the casino," CMAC
"My son said we lived in a crack house…There’s a tiny chip in the wall from the doorknob," KNWerner wrote.
"My dad is a hospice chaplain and officiates a lot of funerals. My son and nephew were asked by their preschool teacher if their papa was retired or had a job. They told her his job was to kill people," Tiffyd wrote.
"My son said "my dad left me and I'm all alone" to a random person at the zoo. My husband was just at work," Shelby.
"I am now in my 70s. In my gradeschool, during the McCarthy era, I told my teacher my dad was a communist. He was an economist," Crackerbelly wrote.
"In Kindergarten, my daughter told her teacher that mommy drinks and drives all the time. Coffee. From Starbucks," Jessica wrote.
"Well I once told my kindergarden teacher a man climbs over our fence to visit my mom when her husband is not home... It was a handy man who came to fix gates when they were stuck," Annie wrote.
Ultimately, McCausland’s story is a fun reminder of how children see things through their own unique lens and, with total innocence, can say some of the funniest things. It’s also a great warning to parents everywhere: if you aren’t clear with your kids about what you do for a living, you may be setting yourself up for a very embarrassing misunderstanding. So, even if you think they know what you do ask them as see what they say, you could save yourself from a lot of embarrassment.
