Mistakes are a Must Stay Focused and Take Mistakes Seriously

The Best Opportunities Carry More Perceived Risks

Don’t be paralyzed by the fear of making a mistake. Understand that the best opportunities usually carry more perceived risks, and distinguish carefully between the risks that matter most and those you can live with. As long as I know the risks I’m taking and the stock prices are compensating me to take those risks, I can live with that.
