Go to school. Get some education.
This really depends on who you hang out with.
If you are staying with your Dai's then go for it. If you are strong and want to make a difference then go to college.

Depends on how good you are on computer programming and coding. I have several friend who got fired (or left by themselves) after few days in work. Consultancies provide you some sort training, but I don't think it will be sufficient if you lack in basic programming skills.
Good Luck.

thank you NepaliScientist and Kaliya for your valuable suggestions.

My advice: go to school. If you are good in programming, study computer science (If that interests you). Then come to Silicon Valley. And work for startups since you are a resident and you won't have as much risk factor as int'l students working in startups. And who knows, boooom !!
Anyways, go to college.
