没有永恒的事实，就像没有绝对的真理一样。
There are no eternal facts， as there are no absolute truths.
The real journey is the one that never ends.

Paranoia is just another word for ignorance.
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.
