I don't know that it is related to "anxiety," which is normally not energizing but debilitating.
I think you all are talking about wanting to get to the goal of feeling good about yourself because you accomplished a major task. Because you want the "fix" of the endorphins that comes from completing a task that has a major impact on your life, you run at full speed to the goal so that you can receive the reward of feeling good about what you did that much sooner.
Anxiety itself -- at least in the sense it is used on this forum to refer to fear and the sense of impending doom -- usually doesn't make people want to paint rooms!
