世界变化非常快。大不再能打败小，而是快的打败慢的。

A pure hand needs no glove to cover it.

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.

The act of writing is an act of hope.

Psychology is the science of mental processes.

If you want to achieve greatness, stop asking for permission.
