Unfortunately, the “get rich slowly” method of working hard, earning a lot of money, carving out a big chunk of it to invest, and investing it in some reasonable way cannot be rushed. (Although in extreme examples where you save more than 50% of your gross income you can shorten the period to financial independence to less than 10 years.) If you wish to become wealthy faster than that it will require you to take on significant risk, such entrepreneurial risk and leverage risk. Done poorly, these methods may be just as likely to make you poor as rich. Done well, you may be able to punch out of a job you hate in less time than it takes to finish medical school.
