Unless you're someone whose entire life revolved around being the hot young stud (unlikely given that you're posting on an ancient video game forum, just saying. Statistically unlikely) or you're so unhealthy that you have a massive influx of issues awaiting you at an unusually young age (possibly more likely for the aforementioned reason), then generally speaking your 30s are far superior to your 20s.
Also a lot of people don't find whatever makes them happy or inspires them until even later, so it's really never too late to get your shit together.
