IMHO, more young people should do this kind of thing (within reason of course). Now that I'm older I realize I didn't appreciate how opportunities to do stuff like this often diminish in later phases of life. Personally, I did have some adventures kind of like this, but in retrospect, I should have done a bit more as I look back very fondly on those times.
Things as simple as talking to a girl on the train and striking up a friendship to saving up some money and quitting my job that I hated and did not want to do to buy a one way ticket to another continent and living out of hostels.
There have been pain points: , a decade later that girl ended up causing me grief when we did not amicably split ties, the trip caused me to encounter scammers on the run from the law that robbed me of some money and almost landed me in French jail by mistake, the switch from a field I got boxed into that I quit to what I wanted to do was painful and took way longer than it should have.
But looking back, i'd suffer through the dark moments all over again because it made me grow. My life looking back thus far was a mostly mundane existence of missed opportunities mixed in with moments of bravery that spiced things up from time to time and for that I am grateful and blessed.
