Happiness doesn’t come from successfully completing simple or mundane tasks; it comes from completing a task that demands your best efforts.

幸福不是来自于做好简单平凡的事情，而是做好哪些需要你竭尽全力才能完成的事情。

When you pour your heart and soul into something and you accomlish that something, the afterglow of satisfaction you feel is happiness. It is the thrill of all your efforts and hard work.

当你全身心投入地做某事，并且把它完成，这种令人回味的满足感就是幸福，是你所有努力和辛勤付出换来的兴奋感。
