快乐者必将取胜，必然如此，因为幸福从来都是孪生。

We do not need magic to transform our world. We carry all the power we need inside ourselves already.

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.

Innovation often happens at the intersection of disciplines.
