Challenges are opportunities in disguise; embrace them and grow stronger.
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.

You get what you give. What you put into things is what you get out of them.
忽略别人可能对你持有的看法,因为他们压根没有在想你。
逻辑学研究不仅仅是关于形式系统,更是关于推理本身的本质。
