Instead of buying a bottle of ketchup, buy Heinz stock. Instead of buying a gallon of gas, buy stock in Exxon. Try stock in John Deere instead. So go ahead and spend your money. Spend as much as you want.
Life is a series of choices.
I'm not telling you to stop spending money, merely to choose how you spend it. Once you get into this habit, you'll develop as much excitement buying investments as you currently do buying clothes. But once you start to buy things that rise in value, you'll never look back. If you think shopping is fun, wait until you start shopping for things that make money for you. If you're like most people, you clip coupons.
