I was in my 20's at the height of the travel bubble running around hostels and such and.. yeah. So many people "looking for themselves" but if you step back and look, it's just hedonism which will never make you happy long term. Partying with other young people who share some parts of your world view and lounging around beautiful places is really really fun for a while, but it's hardly a recipe for a meaningful life. I did certainly gain a lot from those experiences but I also am glad I didn't spend the next 10 years doing the same thing. My current version of it is to move somewhere for 5+ years - really shows you how shallowly you understand anything about a different country while traveling.
