Minimalism

• Spend less than you make
• Buy cheap, reliable transportation
• Spend cheaply on housing
• Don't try to keep up with the Joneses

The bigger the house you buy, the more stuff you have to buy to fill it. Buy an unreliable expensive  vehicle, you'll always be repairing it. You'll always have less stress living below your means. And if you invest the money that you don't spend, your money will grow and you'll make way more in your lifetime than you would have otherwise. 

Remember that your money is your time, and that you have less time than you think. 

Just make sure that you don't obsess about money to such the point that you miss out on the important things in life, like family and friends and God.
