The best way to really gain wealth is to start lots of small, side businesses. These are businesses where you hire people to do very simple tasks. The only reason they will work for you rather than themselves is that they lack the organizational skills that you have. The actual jobs don't matter. As long as they are needed jobs, people will pay you rather than learn how to do the jobs themselves.
For example, almost every household in America has at least one bicycle. Most have two, three, or even four. Every bicycle will get on average three flat tires a year. In a typical block in the Suburbs, there are about forty houses. Let's say those forty houses have 100 bicycles. So 300 times a year, someone will need to repair a flat tire.
Repairing a bicycle tire is simple and can be learned in ten minutes. You can even learn how to do it online. But don't you go changing all those tires. Hire some neighborhood kids to do it. You charge $20/tire (people will pay it) and pay the kid who does the work $5. Believe me, he will be very grateful just to have some money. That's $4,500 for just one residential block. Keep advertising and adding streets to your territory. Pretty soon you will be raking in tens of thousands of dollars every single month.
The beauty is this side-business runs itself. So after you have it up and running, try something else. Since you don't have to put time into these types of businesses after they are set-up, there is no limit to how many other things you can do. Which means there is no limit to how much you can earn!
Who says it's tough to make ends meet?
