一切迷信的根源在于人们只关注事情成功的时候，而不关注失败，他们只记住成功，而忽视失败。
The root of all superstition is that men observe when things hit， and not when they miss， and commit to memory the one， and pass over the other.
History is not the past. It is the present. We carry our history with us. We are our history.
Comparing ourselves to others is a surefire way to feel worse about our own lives.
