If one day you become rich, remember these 10 things. 1. Don't announce it. Quiet money lasts longer than loud money. 2. Give yourself at least six months before making any major financial decision. 3. Don't mistake a cash windfall for permanent wealth. Build systems that keep producing income. 4. Buy assets before you buy luxuries. Let your investments pay for your lifestyle. 5. Don't rescue every friend and relative. Help people in ways that don't destroy your own future. 6. Increase your security before you increase your spending. 7. Keep learning. The knowledge that built your wealth is what will protect it. 8. Teach your children how to create wealth before they inherit it. 9. Remember that every expensive purchase has a lifetime cost, not just a price tag. 10. Stay humble. The market has a way of humbling people who believe they'll never lose. Getting rich can happen in a moment. Staying rich is a decision you make every day.
