永远不要停止学习；一旦停止，你就会过时。
Never stop learning; the moment you do, you become obsolete.
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.
在物理学中，最简单的解释往往是正确的。
Let me live truly, my Lord, so that death to me becomes true.
