DON'T…

Don't underestimate yourself.

Don't refuse to listen.

Don't bottle things up.

Don't expect life to be fair.

Don't stick your head in the sand.

Don't beat your head against a brick wall.

Don't think the grass is greener

on the other side.

不要低估自己。

不要拒绝聆听。

不要遮遮掩掩。

不要期望生活是公平的。

不要逃避现实。

不要自寻烦恼。

不要见异思迁。
