卷首語
作者：
Perseverance does not always mean sticking to the same thing forever. It means giving full concentration and effort to whatever you are doing， right now！ It means doing the tough things first and looking downstream for gratification and rewards. It means being happy in your work， but hungry for more knowledge and progress. It means making more calls， going more miles， pulling more weeds， getting up earlier in the day and always being on the look out for a better way of doing what you’re doing. Perseverance is success through trial and error.
毅力並不總是意味著永遠堅持做同一件事。它意味著無論做什麼事情，你都要立刻全心投入、竭盡全力；它意味著先做艱苦的工作，再去期待隨之而來的滿足和回報。它意味著開心地工作，渴望更多的知識和進步。它意味著多打幾個電話、多走幾裏路、多除草、早起床，意味著總是尋求更好的方式去做你在做的事情。毅力就是經曆考驗和過去的成功。
