"Books are the quietest and most constant of friends; they are the most accessible and wisest of counselors, and the most patient of teachers."
书籍是最安静、最恒久的朋友；它们是最易接近、最睿智的顾问，也是最耐心的老师。
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.
Survival can be summed up in three words – never give up. That’s the heart of it really. Just keep trying.
