When I first started, I too worked on one at a time but was too anxious to finish up to get to another project. Now I have several going on at a time. 4 are BOMs and one is a monthly banner (see avatar), plus a bunch of Yo Yos for while I watch TV. Then I have a quilt that needs binding and another that has to be assembled. I am a finisher too. The smaller projects help me feel a sense of accomplishment while doing something on the larger ones. Plus, if I am tired of one project, I just go to another.
