I had a similar experience, travelled a lot, many different jobs, changing relationships - but I see myself as a success, would not want to change that experience for anything. In my 40s now with kids and loving wife - still moving jobs and countries (but with my family this time) I couldn't be happier.

Yes, I had periods of desperations and self-doubts but I would have had those also had I stayed in the same place focussing on the "career ladder". I'm happy I following my urge to see the world and embrace chaotic life.

"Wasted live" is nothing but a question of perspective.

I don't have debt though - that part is indeed worrisome.
