Same, spent most of my twenties enjoying the world, and focusing on business. I wouldn't do it any other way, while a lot of my friends are tied down with houses and families in their twenties.

I'm jealous of one thing though. They got to spend their twenties with the partner they'll spend the rest of their life with. I've had a lot of great times in my 20s, but those memories are mostly with people that have come and gone. If you're meeting someone and starting a family in your thirties, it needs to move quickly, and women always want to have children before 35. So, if you meet someone early thirties, you're spending a quick year or two together, and starting a family. If you meet early twenties, you could spend at least a decade growing and experiencing a lot together before starting a family.

So, that's my one regret, I'll never be a 40 or 50 year old, being able to reminisce with my partner about the fun adventures we had together in our 20s.

However, you can't have it both ways, and I imagine people that settle down or start a long term relationship early feel like they missed out on a few years of independent freedom.
