You start out with energy, sag in the middle, and finish with enthusiasm:
Yes, your confidence builds as you start your projects and see them materialize. But something seems to happen to you in the middle of each and you may find yourself "belly aching" about all you have to do. Nevertheless, you make steady progress and you show common sense and a willingness to forge ahead. As you near the culmination, you view the goal as almost accomplished. This inspires you to cross over the finish line with renewed enthusiasm.
