I find as I do art, or even household chores, there are two approaches. One is to say I need to clean that closet and not rest until it is done. The advantage of this is that it gets done and there is a completion because of this. The disadvantage is that you are completely goal oriented, and the finish line is all that is important, and your journey towards the goal is not a relaxed one. The symbol becomes more important then the way to do it.
The second approach is to do a little every day, putting in your time, not worrying about the results, and trusting that they will come. The disadvantage here is that sometimes, during the avalanche of things to do, projects don't get completed. Distractions, crisis, accidents all happen, and that closet might not get finished. Sometimes without that finished goal in mind, the effort just diminishes.
