Work hard. When starting out I had two jobs. Bought broken games, fixed them and routed them then sold them for a better broken game. One game turned to two turned to 20... then ex issues reversed that to 0.
Today I have scraped and clawed my way to a very comfortably paying job. We have a rental and our primary house that we are nearing pay off and stay well within our means. Currently back up to 4 (two playing two projects). Once the rental and our house is paid off... gonna likely go nuts.
