If you smile when no one else is around, you really mean it.
独处时的微笑，才是发自内心的。
Recently I found I seldom smiled when I was alone.
Most often I felt depressed and frustrated due to the obstacles I met both in life and work.
And I become more and more pessimistic, I wonder whether I can overcome these difficulities in the near future.
Nothing is satisfying.
Be cautious, it seems I would be totally lost in such negative feelings and I can't free myslef to have something different in my life.
Maybe it is a wrong thought: I always want to get something in return and get paid for everything I do.
With self-discipline most anything is possible.
只要严于自律，大部分事情都可能做成。
With self-discipline and a little bit of luck, we can do most things.
Sometimes only self-discipline is far from enough.
I have witnessed many people who are strictly self-disciplined and working very hard but still accomplish nothing satisfied in their life.
And I also know a lot of people who don't have to work or don't have to make efforts in their life but still possess amazing amounts of weathly and power.
This world is totally unfair.
Maybe the best thing I should do is to do my best and then listen to the heaven.
