  • Make good decisions even with incomplete information. You will never have all the information you need. What matters is what you do with the information you have.
  • Always trust your intuition, which resembles a hidden supercomputer in the mind. It can help you do the right thing at the right time if you give it a chance.
  • Don't make small investments. If you're going to put money at risk, make sure the reward is high enough to justify the time and effort you put into the investment decision.
