You can't just keep doing what works one time, everything around you is always changing. To succeed, stay out in front of change.

The only way to do great work is to love what you do.

小人办事，处理的原则是私利，合于私利的就看作利，违背私利的就看作害；君子办事，衡量的标准是道义，合于道义的就看作利，违反道义的就看作害。

“I give my whole water in joy，“ sings the waterfall， '' though little of it is enough for the thirsty。''

The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but rather a lack in will.
