A day without sunshine is like night. 没有阳光的白日如同黑夜。
The past is gone and static. Nothing we can do will change it. Thefuture is before us and dynamic. Everything we do will affect it.
You are the only exception. 你是唯一的例外。
What gets us into trouble is not what we don't know.It's what we know for sure that just ain't so.
