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.

失败使我的内心产生一种安全感，这是我从考试中没有得到过的。失败让我看清自己，这也是我通过其他方式无法体会的。我发现，我比自己认为的，要有更强的意志和决心。我还发现，我拥有比宝石更加珍贵的朋友。
Boundaries define us. They define what is me and what is not me. A boundary shows me where I end and someone else begins, leading me to a sense of ownership.
