翻译：天的运行刚健不辍，君子应当像天那样自强不息。
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.
人生的伟大任务是学习主的旨意，然后遵行它。
