Started a business, made some money, took that and bought the building my business is in and rent the building to myself. Started a sister company for my business that compliments the work I do and was paying someone else to do. Bought a trailer park, and collect rent. I have a condo I rent out and a house that is about 1/3 of what I can afford, and about 1/5 what most Americans that make what my household income is would buy. Moral is, don't overspend, save and invest, and keep something on the side such as renters to keep you liquid. Get a good CPA and a good financial advisor. I'm not rich, but am comfortable at 32, and will be what most consider somewhat wealthy by 40 at my current pace.
