On motivation: "I strongly believe that missionaries make better products. They care more. For a missionary， it's not just about the business. There has to be a business， and the business has to make sense， but that's not why you do it. You do it because you have something meaningful that motivates you."
我坚信倡导者能够创造更好的产品，因为他们关心的东西更多。对于一个倡导者来说，一个项目并不仅仅只是一个生意。他的事业与生意有关，而且必须把生意做好，但生意并非他做这件事情的原因。你做某一件事情，是因为它对你来说是有意义的，那才是你的动力。
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.
