Not only is this unrelated to the OP, but it's also not actionable advice. Sounds like you got lucky and got a bunch of great stock. That's not something most people can count on, and housing in American urban centers only goes so low.
And travelling is cheap as well, I have a friend who is travelling long term for like $300-600 a month, including all the transportation costs, etc. (The opportunity cost of not working is obviously much higher though.)
But I sure didnt enjoy it very much.
But if you lived on rice and beans in the cheapest place you could find while making a 6 figure salary... Saving a very significant sum every year would be possible.
This is in fact pretty unactionable unless you are planning on boondocking during your career and retirement - at which point - why bother with post secondary education and a white collar job in the first place, just boondock from the getgo.
