I'm increasingly convinced that the willingness to change your mind is the ultimate sign of intelligence. The most impressive people I know change their minds often in response to new information. It's like a software update. The goal isn't to be right. It's to find the truth.
People really don't realize that "you reap what you sow" is real and nothing goes unseen. The way you treat people, the things you do in private, the intentions behind it all etc.
