You can only find out what you actually believe (rather than what you think you believe) by watching how you act. You simply don’t know what you believe, before that. You are too complex to understand yourself.

The greatest performance improvement of all is when a system goes from not working to working.

Never stop believing in yourself.

The best way to predict the future is to create it.
