Take precautions when taking risks.
Most people are terrified of losing, so they don’t take any risks at all. However, this actually limits your success significantly, since if you do not take risks, you do not give yourself the opportunity to win big. Keep in mind that you will sometimes lose some gambles—but this should not hold you back from trying again.
Follow the above rules and you will increase your chances of winning big while decreasing your chances of losing out.
