At this point its pretty clear I'll never advance as far as I would like in my physical hobbies without sacrificing a lot in my other aspects of life.
Food and cooking is something I can't really explore beyond a interest and just being an eater. I think this ties back to travel too.
There are a lot of things that are really tied up in academia. I got pretty interested in philosophy of mind last year but my enthusiasm died pretty quickly when I realized there is really no where for me to take this hobby other then satisfying my own curiosity. Somewhat similar in programming, more paths seem unobtainable. I don't think I'll ever do something like work on operating systems, anything that intersects with electronics or cutting edge. I don't have the education or even a way to test the waters. This ties back to before with life's milestones, I don't know if i feel comfortable about a risky career switch when Im making tons doing what I am already.
thats off the top of my head
