Change Your Thinking, Change Your Life: How to Unlock Your Full Potential for Success and Achievement

Practice Zero-Based Thinking
You need the courage to practice zero-based thinking continuously
in your life. Ask yourself, “Is there anything in my life that, knowing
what I now know, I would not get into or start up again today if I
had it to do over?”
There are situations in every person’s life that, knowing what
they now know, they wouldn’t get into again if they had to do it
over. If you decide that there is something you wouldn’t get into
again, your next question is 
how do you get out and how fast?
You cannot make a great life for yourself if, right in the middle
of your life, if there is something that you wouldn’t even get into if
you had it to do over again. And you always know when you are
dealing with a zero-based thinking situation. It causes you a great
deal of stress. It preoccupies you continually. It sometimes keeps
you awake at night and dominates your conversation. You always
know what it is.
