信任的人不忠诚，忠诚的人不信任。 

The most important thing in mathematics is to ask the right questions.

人は、自分が選んだ道に責任を持つべきだ。

At a restaurant do you order what you know is great， or do you try something new？ Do you make what you know will sell or try something new？ Do you keep dating new folks or try to commit to someone you already met？ The optimal balance for exploring new things vs exploiting them once found is: 1/3. Spend 1/3 of your time on exploring and 2/3 time on deepening. It is harder to devote time to exploring as you age because it seems unproductive， but aim for 1/3.

Success in business comes from understanding both the numbers and the people behind them.
