According to one commenter, one of the biggest mistakes many people make in their 20s is not saving enough money for later. “Savings, 401k, whatever,” one person said. “Just invest for yourself.”

A few people echoed saving for the future, saying they can’t stress enough how much it can help to maximize employer matches in one’s 401k early. “I have coworkers who are in their late 60s and only started in the last ten years and do not have much,” one said. “That’s also why they won’t retire or feel they can’t.” 

3: You’re Gonna Go Far, Kid

“Life is not a race,” one person advised. “It doesn’t matter who’s getting married, who’s moved out from parents house, who has a kid. You go at your pace. Don’t think you’re behind anyone else.”

Wrecking your ears with excessive noise exposure is the worst mistake a person can make in their 20s, one commenter says from experience. “Even if you don’t care about losing your hearing, you don’t want catastrophic tinnitus. It’s completely disabling. And nobody tells you that you can get it years or decades after the noise exposure.” 

6: Invest in Yourself

Another person says that not saving enough money left them with significant financial regrets later in life. “Pay yourself first. Don’t work the rest of your life.” 

7: Fit at Any Age

The heart attack you have at 50 doesn’t just magically show up, one person warned. “Cardiovascular disease is from years of buildup from not eating right and exercising.” Another said not to let that discourage you. “I started running and cycling and eating somewhat better when I was about 43. I honestly feel healthier, younger, and fitter than in my twenties.”

8: It’s the Small Things

From tiny acorns, mighty oaks grow. One person said not enough people in their 20s make small changes and stick to them, like trying a new hobby or putting savings away. “You must do little things every day and just don’t stop. It’ll add up in your 30s, and you’ll be so grateful even later.” 

9: Blowing Money

Watch your spending, twenty-somethings. One person says the worst mistake people in their 20s make is racking up credit and debt. “It’s too easy to buy things you can’t afford.” Another adds that they also wish they understood this in their 20s. “I was very careless with money.”

10: Pump the Brakes

Don’t treat your body like it’s a rental, another warns. “Look after it. You will be living in this body for many years to come,” they said. “Don’t burn out the clutch by 27 and live with the consequences for 60 more years.” 

11: Work It Out

According to one person, sticking to a career you hate just because it’s what you’ve always done is the worst mistake. “It’s never too late to change your career path, and if you’re not enjoying it now, do you think that will change in another 20-30 years?

12: Move Around

Getting too comfortable in your current job can lead to problems down the road, one person says. “This isn’t the 1950’s where corporate culture rewards loyalty. Don’t be like me and become obsolete, making life scary and job hunting depressing – It is daunting to recover from.” 

13: Never Stop Growing

If you’re in your twenties and think you’ll be the same person forever, you’re misguided, according to one commenter. “You are not who you were at 20 when you turn 40. No one ever is. Keep recognizing your growths, strengths, and challenges.” 

14: Live in the Moment

Focusing too much on the future can distract you from the life you want, said a wise soul. “Right now always has its great moments. Right now has its own joys. Work for what you want, but live right now.”

“If you aren’t taking dental hygiene seriously in your 20s, you will have a bad time later in life,” a pro-dental care commenter warned. “Amen,” another added. “I’m in my 40s, and I’m looking forward to false teeth – that’s how bad it’s gotten.”
