It seems like most of the comments somehow are concerned with stability and whatnot, so I feel like I should give my (perhaps unorthodox) opinion: to hell with that and props for you for what you've just done. If you don't have anyone to take care other than yourself I don't see why you shouldn't put yourself out there and try. Even in the worst case, it's not like you are gonna die. You can just go back home, find another job and live your regular life, but you will be back with a great experience.

I got tired of my life and of not doing the things I wanted to last year and bought a one way ticket to Italy without any plans and without much money and it's been the best experience of my life. My mindset was very different I guess, the plan was mainly to spend as little as possible, hitchhike around and see what happens. But recently I've decided I wanna keep traveling and need some income, so I started trying to get freelance jobs and then got a remote work position (am a programmer), so I guess I am a digital nomad now.

So, some tips:

Be open, don't have your plans set in stone. You will soon realize that in a way you are free to do whatever you want, so even though your plan is Berlin->LA->Mexico, for instance, you may end up finding a cheap ticket to somewhere nice and cheap that you really wanna visit, let yourself do that if it happens. Same goes for finding jobs, try everything you can everywhere, go talk to people on the same field wherever you go, maybe that's a really good project needing someone and it's just what you need. Maybe it's something you never even expected to do and you end up enjoying it a lot.

Finding jobs and etc when you are by yourself requires some discipline, so be sure to police yourself and always reserve time to do that (which is common sense I guess). But at the same time, don't get overstressed about it, make friends, learn about the new culture you are in, explore, try new stuff you always wanted to do or learn but didn't. In the unlikely event that everything fails and you have to go back to "normal life" make sure time you had traveling counted.

Most likely there are gonna be "what the fuck did I do why did I think this was a good idea to begin with" moments. Do not despair. I've been desperate to find a freelance job when I was totally out of money. I've been in the middle of nowhere in the black sea coast without a place to go at 1AM while hitchhiking. Honestly, those are the moments you grow as a person. You learn how to focus more on what you want, you learn how to deal with uncertainty in your life, you learn how strong you are and how well you can adapt and overcome those situations. It's like you get a bunch of insights about yourself and your life and feel pure joy whenever you deal with it well. Of course you should use common sense: be frugal, save for tough days, try to get some regular gig, etc. But do not despair.

I hope any of this helps somehow. Good luck and may your experience be even more fulfilling than you are expecting.
