Well, it was a very good experience. The few times I slipped up I certainly paid... for instance, because I promised to bake bread for my church's Easter breakfast, it was a real hassle because I ended up not even being in town for the event. So I had to get up at 5am on Saturday morning, bake the bread, then drop it off at the church on our way out of town. Meanwhile, because I was overloaded, I forgot a whole bunch of other things, such as Easter egg dye, the 18 eggs that I had boiled, and birthday presents for my niece and nephew. So I had to go shopping for those things all over again. And, now I have to return the egg dye + presents and eat 18 more eggs.
Overall, I finished several projects that I had started a long time ago. I was forced to confront the reasons why I gave up each time, and either solve them or decide it wasn't a big deal. This new emphasis on finishing projects is reducing clutter, saving me money, and is making me much happier.
Will I continue? It would probably be wise to go for a month extension. However I am wrestling the impulse to volunteer for the kids' school spring fair, church tag sale, and many other events. Not sure if I will be able to stop myself!
