It takes a great deal of discipline and energy to make new choices, and to keep wanting and making those choices every moment of every day; when you're off the familiar tracks, it's easy to just coast around in little circles, without practiced vigilance.
In other words, if you keep doing what you are doing you will keep getting what you are getting. If nothing ever changes then nothing ever changes.
I told my psychiatrist that everyone hates me. He said, "That cannot be true. You haven't met everyone yet!"
