I'm not an expert or anything, so take my personal opinion with a grain of salt. If you aren't happy, do something about it. Otherwise, in a couple years, you will wake up miserable feeling like you have cheated yourself out of the most precious thing we can never get back - time. You are the CEO of your own life. Enjoy your journey, take risks, and don't be afraid of being a little foolish - so long as it is in a smart way. Good luck!

(FWIW I skipped out on traditional job offers after getting my masters to begin a startup)
