My Father worked as an engineer from when he got out of the Navy until he retired. He used money from his Navy pay and from his regular pay to buy stocks. Let’s just say that since his estate has been disbursed, I’ve given serious thought to closing my business and going straight to starting my film production company.
All that from money he earned than invested.
but your last sentence is wrong. Many people have become financially independent by working regular jobs and earning regular paychecks. The trick is to spend less than you make, save and invest wisely and for the long term. Starting your own business is a very speculative way to try and achieve financial independence – 80% of those that do this – do not succeed and, in fact, wind up the business.
