【译文】 孔子说:“我十五岁立志于学习,三十岁有所建树,四十岁不困惑,五十理解自然规律,六十明辨是非,七十随心所欲,不违规。”
I think prime numbers are like life. They are very logical but you could never work out the rules, even if you spent all your time thinking about them.
痛苦是不可避免的,但受苦是可以选择的。
当你失败时,那就是你站起来再试一次的时候。没有理由就这样倒下。
Success is not final, failure is not fatal: it is the courage to continue that counts.
学习的唯一途径就是行动。你需要知道的一切,都已经通过你的旅程学会了。
