The first mistake is to constantly complain about things.

People who get satisfied with only complaining stop doing anything that actually makes a difference. In the end, these people achieve nothing.
那些仅仅抱怨一下就满足了的人，是不会去做真正有用的事情的。最终，他们将一事无成。
The second mistake is to constantly try to outweigh everybody around you.

If you take every pitiful chance to prove yourself better than others, you'll only make yourself miserable in the end.
如果你非要抓住每个可悲的小机会去证明自己比身边的人行，你最终只会把自己弄得惨不忍睹。
The third mistake is to be kind without any condition.
第三种错误是“无条件地善良”。
There is too much kindness in this world.
这个世界上的善良已经够多了。
Some of them are worthless.
其中有一些是没有价值的。
What this world doesn't have enough is rationality.

Kindness without reasoning is the same as evil.
无条件的善良与邪恶无异。

所以你有犯过这3个错误中的任何一个吗？
If you have, now it's the time to stop.
如果有，是时候停止了。
