I actually disagree with most of the advice here counseling you not to quit. It sounds like you would be able to find a similar job with similar income if you quit, tried to start your own project, failed, and re-entered the work force. If you are at a life stage where the opportunity cost of trying to start a company for a year is approximately one year of salary, then I would try it. Unless you have dependents/need a steady income, then it is probably too risk-averse not to try collecting new experiences. A strong suggestion: I would find a cofounder or someone else to work with before quitting or trying a startup on your own. Basically: if you are secure in a high income bracket, you might want to optimize more for exposure to positive, exciting opportunities, rather than play super-conservatively in a way that minimizes variance, may or may not maximize expected value, but certainly eliminates exciting upside.
