War is an ugly thing， but not the ugliest of things: the decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth a war， is much worse.

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 best way to predict the future is to create it.

如果你不能改变它，意见有什么用？

在对抗现实的战争中，想象力是最强大的武器。
