By failing to prepare, you are preparing to fail.
不做准备，那就准备失败吧。
How does the case when you had prepared, but you still failed?
Maybe that just because you hadn't prepared enough, you hadn't taken all the cases into your account.
You didn't fail in all aspects, you just failed in some, and you still got something, experience and knowledge.
Just like me, it seems that I have failed all the times, however, if compared to many others, I am still a winner, or a lucky dog.
Because I still have learned something and have gained some knowledge and experience through the process I prepared for something I didn't get.
No man is rich enough to buy back his past.
无论多少财富，都不足以赎回过去。
When we aged, the past often came into our memory despite ourselves, we might feel regretful for something we hadn't done in the past.
Perhaps we thought if we could go a little further, or if we could be a little braver, things would be different.
Oh, how many things we had missed.
But is it useful to cry for the spilt milk?
No, nonesense.
No matter how regretful we are for the past, we can't bring anything back.
So, the most important thing is to live the current moment well, just do our best at the current moment.
