Having a job you like is more important than living somewhere cool (and personally, I've always found Austin to be highly overrated as far as America's cool cities go). I had a corporate job out of college that I loathed, and I took a giant pay cut to go to grad school and get into a field I love. Not being hyperbolic when I say that in 16 years I've never had the fuck-I-hate-Monday feeling. The best advice I can give to a younger person is to figure out what it is you like to do, and then figure out a way to make money doing that. Nothing better that you can do for your wellbeing.

As to living with your parents or not...guess it depends on the relationship. I would rather be poverty stricken than live with my mom. Stomaching Hot-N-Readys for years on end is a small price to pay for peace of mind. I moved out on my 18th birthday, and we've had a good relationship ever since, after hating each other for years.

There are a lot of niches to fill in the world, and if you love computers and coding or whatever (I don't speak that language so just piecing together what I can from your post), then give that a whirl before trying the coffee/gaming gig. I'm sure whatever your other interests, there are some ways to use your coding skills to contribute. Using your highly honed skills to create a change in the world that you want to see will be a gift that you never tire of. Trust me. Speaking from experience. Your skills are a tool, and using them to advance a cause you believe in (doesn't have to be world changing--I'm talking about personal things), even if only a little, is something you won't regret.
