I'd think the answer would depend on which of the top 3 tech companies you work for: Apple, Samsung, or Foxconn.
Edit: Let me try a more helpful response (though I did intend to make a point there). You seem very focused on what you have: a good salary, a top 3 education, a job at a top 3 company. Things you expect should make you happy, basically, but you aren't, and this is confusing, and it's always scary to give it up if you haven't figured out why those things don't make you happy. But IMO, if that interpretation is correct, it's more important to attempt to find things that do make you happy rather than dwell too much on why the things you have, which are often equated with success in our culture, are not doing it.
