The best way to be rich, is to live cheap...
And that is the truth. I meet lots of wealthier people in my line of work, and most have one thing in common, they are cheap. They consider every penny as an potential investment.
That is also why most lottery winners lose it all, they only know how to spend. There was an economics study years ago that figured even if you took all the money in the world, and divided it evenly to everyone, within 5 years the wealthy would be wealthy again, and the poor would be poor again.
