Creating joy even when doing crappy tasks

I can create joy in the most miserable of tasks. If I have committed to a task, or an objective that I am committed to requires that I do a yucky task to accomplish the larger goal, then I am going to do the task. The only question is whether I am going to do it with enthusiasm/joy or reluctance/negativity. I am choosing enthusiasm and joy. What task are you hating, that you could decide to be joyful about?
