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.

我们活着就是为了改变世界，否则还有什么意义？

Leadership is like pruning: sometimes you must cut back to allow stronger growth.
