Once you quit trying to develop a habit, you can either forget about it and move on or you can come back and try again. In the case of habits that require will power, the costs of coming back to try again are SO MUCH higher than recommitting everyday to continue with developing your habit. So most people take the first route and stay fully away from the habit for a long time.
The same thing is happening with me. I finally got myself to re-start one of my old initiatives today and the resistance is just too much.
Do it right the first time… don’t break the chain.
