Rich people know this. Wealth is accumulated, re-invested, used wisely and given away. Let the millionaire athletes and folks who win lotteries buy the fancy cars and flashy jewelry. Get rich slowly. The key to great wealth is to minimize income, while maximizing your assets.
Income is taxed.
Pay lots of taxes. No, I'm not talking about paying more than you owe, but pay every cent the law requires. Use the law to your advantage when you can. But juggling the books to hide income or save a few bucks, wastes your time, wastes your energy, creates fear of getting caught, and makes you cheap. Give it away.
