I'll go out on a limb here, risk the flaming. I'm ready to go now, scheduled to retire, leave walk away, whichever in June. I've made a comfortable couple, few million. Took time. Mistakes. Successes exceeding failures..
Before I could do any of that I had to see life, money differently. For me "Rich Dad, Poor Dad" was an eye opener, paradigm shift. Vital you do that and commit to change. Next was Milt Tanzner's "Real Estate Investments and how to Make Them" for great intro to math, business. I made it in rental properties, small but high end 2 to 4 places in SOCAL. Get the head in the right place, the rest will follow. Also best to be an individual of commitment and higher energy than average with a hobby that you're committed to.
Good luck,
Jamon Grande
