The message is not that you must finish all of your projects, but that you must decide whether you will finish them or not. If you decide to finish them, then just do it! If not, then store it away somewhere out of sight. If you want to go back to it, you can always pull it out again. Unfinished projects create clutter, and for me (and a lot of people I know) clutter depresses me and makes me less productive. I'd rather have unfinished things filed away somewhere, than out in the open getting in the way of my active projects.
