Yesterday is not ours to recover, but tomorrwo is ours to win or lose.
我们无法重拾昨天，但我们可以选择赢得或者输掉明天。
Even if we can go back to yesterday, we might not be able to change the current situation.
It may be unavoidable for most of us to encounter setbacks and failures, but even the worst situation may have some positive effects, only if we can consider it as an unecxpected opportunity to know ourselves and find out where the problems lie.
For myslef, whatever I do would never make up the loss of yesterday, so it might be a good choice to let the past be past and just stand on the earth.
Try to understand the deep meaning of self-management, and scientifically comprehend the process of self-management, then form a system of self-management, so that we can have more secure footholds in this highly competitive society and gradually become a man of great use to the society.
As long as you are being a copycat, you will never be the best copycat.
你如果只是在模仿他人，就永远做不到最好。
From Eric Thomas.
For many smart advice, it is easier to say than to follow, just like this one.
To be unique, certainly very wonderful.
But for some people, even to be a good copycat might be a very difficult task.
If you can't become a leader, there is no harm to be a good follower.
