"What are the mistakes you made in your 20s that you don't want anyone else to make?" originally appeared on Quora--the place to gain and share knowledge, empowering people to learn from others and better understand the world.

Answer by Andrew Ferebee, entrepreneur, high-performance coach, and podcaster, on Quora:

I turned 30 last year.

As I spend time looking back on my 20s, I don't have many regrets.

I built the business of my dreams, developed a strong body, have an amazing social circle, a beautiful girlfriend, and I'm proud of the person I've become.

But just because I don't have many regrets doesn't mean I don't have any regrets.

Even with the successes I've experienced, there are still a few things that I regret about my 20s....

Here they are.

(P.S. I've written a similar response you might enjoy where I detail the "25 Things I Wish That I'd Learned Before 25.")

1. Not Traveling More

This might sound cliché, but your 20s are the best time of your life to travel and see the world.

I traveled the U.S. pretty extensively, but I never left the country outside of a few runs down to Mexico.

In hindsight, I wish that I'd pulled a Tim Ferriss and disappeared to Thailand or Colombia for a few years while I built my business.

I will definitely go on some epic trips over the coming years but there's something magical about being a solo 20-something with nothing but a laptop and a suitcase.

And I missed out on that experience.

Do yourself a favor and travel.

Go see the world.

Volunteer your way across Europe. Backpack across South America. Go build a lifestyle business from Southeast Asia while you still can (and while it's still so damn cheap).

It doesn't matter where you go, just GO!

2. Staying in the Wrong Relationships

I don't regret any of the relationships I had in my 20s. They all taught me valuable lessons and helped me become the man I am today.

But I do regret wasting my time by staying in stagnant and downright toxic relationships.

I wasted years of my life with women who I knew were not a good fit for me and my life. It wasn't that they were bad people, but we simply weren't the right match.

At the time, I was too scared and naive to pull the plug and move on. I was operating from a scarcity mindset and worried that I'd never find another woman like them.

I was wrong.

I actually wish I had avoided seriously dating all together for the first 75 percent of my 20s.

Unless you are absolutely head over heels in love with someone and you and everyone else around you believes in the potential of the relationship, I'd recommend avoiding seriously dating in your early 20s.

Chances are, it will only lead to regret and wasted time. Instead, try to have as many experiences as possible.

Casually date lots of people (not just hookups here) to see what types of men/women you enjoy spending time with and which ones drive you absolutely crazy.

Take it slow and fall in love with yourself before you fall in love with someone else.

You'll be better off for it.

3. Not Taking Care of My Physical Health

Although I remedied this one in my mid/late 20s, I wish I had done this sooner.

Your physical health is one of the only things that is a constant in your life and it has a HUGE impact on other areas of your life.

I regret taking it for granted and wasting so much time drinking and partying when I was in my early 20s.

Lift weights, drink protein shakes, and sprint your happy ass off in your 20s and you won't regret it.

Avoid drinking to excess and using hard drugs. Sleep nine hours a night. Drink plenty of water. And watch what you eat.

You will look, feel, and perform like an absolute champion.

That's really it...

A few honorable mentions that my clients regret (but I never personally experienced) are:

  • Not saving more money in your 20s
  • Getting married to the wrong person
  • Getting hooked on substances like cigarettes or drugs
  • Not working hard enough on the things that matter
  • Letting your family dictate what you do
  • Getting in debt to go to college for a degree you will never use

Hope this helps! Go out there and rock your 20s.

They are a magical decade, and if you play your cards right, they will set you up for an incredible life.
