Incoming anecdote..
My uncle, Peter Dussmann, started out cleaning offices, then started an office cleaning company, than bought an office building...now he owns one of the largest service companies in the world (50k+ employees).

When you make money it opens up other opportunities. How you leverage them is what matters.
That said, I'm 1000% Uncle B.
