Prioritizing projects based on available time is always the first issue when I look at what I have on my plate. Sometimes my nice "plate" arrangement is destroyed by the addition of some piece or separate project that I have to push to the top. Then it becomes prioritizing based on my ability to make steady progress on projects [albeit sloooooowwwww] instead of stopping one to start another. I avoid stopping and halting any paid or deadline volunteer project. This means that the projects that stop are the "fluffy" ones, the fun ones, the ones that I would be doing if the dishes did themselves and I did not need to make money. That said, because I have a great deal of overlap between what I consider fun and what I do for work, there is often the situation where an instructive fun project must be continued so that I am not slower than slow on the "real" thing. Now, if only I could solve the problem of not having adequate chunks of time to work holistically through a project instead of 15 minute increments of repeating the same task over and over until I feel fluid.
