I work very hard to be good at what I do. My current focus is on learning as much as I can, regarding whatever it is that needs my immediate attention as well as aspects that may help later with a startup (if it ever comes to that). I am single with no debt whatsoever and I pack away as much as I can save (I am somewhat of a minimalist and live very frugally).
Regarding HN - It probably is the most relevant source I have found. Lot's of great advice and articles, lots of motivations (@patio11 comes to mind) and most importantly the company of (somewhat [1]) like-minded folks.
[1] - I say somewhat mostly because I doubt many others are people attempting to immigrate.
There are many thing to master in this life. Business is just one, you name others(hint: family, prof skills, sports, etc). Think about it.
