More than just expecting to break your habit, I think the crucial piece is planning what you will do once you have. The most dangerous moment in building a new habit is the moment when you realize that the best case scenario (aka sticking with the awesome new habit) is just not going to happen. For me, unless I have my Plan B ready to go, I tend to just revert to the status quo or worse (since I already failed, why not go all out). Having the Plan B - a glorified "if failure to complete Plan A, then do B" - already articulated lets me immediately move on to the next thing without beating myself up. This was really helpful for me when I was getting going with a regular early morning jog. If I didn't get it in before work, plan B was a quick run after work before I drove home. The latter wasn't the habit I wanted to stick, but it helped me forgive myself the lapses until morning running became a habit.
