在商业中，如果你不前进，你就在落后。

Every one is their God,if you give up on yourself,who else will save you?Every one is busy,some are busy livig,some are busy dying,and you, who are busy chasing fame and fortune,who are busy with daily necessities,try to stop to think a second:if your brain has been institutionalized?Where is your God?

Grit is passion and perseverance for very long-term goals.
