Well I spent about 8 months in
Thailand with 9k$ back in 2011. You can live in Chiang Mai or Chiang Rai renting a place for 100$ a month (there are smaller local places down to 60-80$ a month but it'll be a slum). It's even possible to relax on some Islands like Koh Chang, for up to a year, with this budget (well you'll probably waste 50% of it for flight tickets... but you could earn something in Thailand, just do a research on the forums, people do various types of work like tour guides, it might be slightly illegal to work as a tour guides but the top penalty is deportation lol which means free tickets back home?
). I know many Russians who had same budgets as you, and went travelling... Just learn as skill you can earn income with, on upwork.com / freelancer.com / fiverr.com / etc' and you can earn 5-10$/hour doing stuff like writing texts/articles on any topic, drawing something, maybe 3D modelling but it's more difficult, video editing and photoshop, even manual QA (
Homepage - TesterWork) where you just repetitively test applications and report bugs, it can be paid nicely and people use such jobs to start from scratch. I personally was Flash games developer and started from nothing after school, basically same situation as yours - in 2006, finished high school, no university degree, just learned Flash and scripting online within a year, started making banners/websites/games earning barely 500-800$ a month. Now I live and work in San Francisco with 15000$/month salary and it's all just hard work and dedication (well not THAT hard work, I never spent more than like 10-12 hours a day, in my worst days, working on something difficult).
Your best bet is of course online jobs like design, data analytics (Tableau/Big Data), scripting (python/javascript), QA (manual work with apps, easiest entry job), even gaming QA, to play games and report bugs
both fun and profit. Just need to look for it, read a lot online about what other people do for a living online, look at all categories on Fiverr - there are even these who do a funny dance or funny voices and sell it for 5-10$ a piece
some birthday greetings and such, even paintings and drawings with personal message - people buy it as a gift for someone else since it's a personal performance it's kinda cool.
Good luck I wish you the best
