The secret to getting rich and staying rich is to always live just below your means, no matter how much you make.

when people make more, they buy more and more expensive things and go into debt to buy more and more expensive things.

however looks can be deceiving.

they have physical "things" but are still short of time
when you talk to them, they even look down on other people who don't have designer handbags,  or cars and don't realize that they are the ones who are actually poor.

create your ideal lifestyle, then figure out how much it costs and don't worry about the material crap.
