"I have a very hard time getting organized because one thing always seems to be contingent upon another. Any suggestions?"
by Sandy Maynard
Like many ADDers, you tend toward "circular" thinking. One task is connected to another, and another, and so on. Eventually, everything becomes connected in an overwhelming mess. The best way to interrupt that circular pattern is to insert a "starting point."
Instead of dwelling on what you can't do, identify what you can. From there, break your problem down into other manageable steps. For example, begin by moving the bookcase to the garage or porch where it will be painted. The next steps should flow from there - sanding it, buying the paint and brushes, and so on.
Watch out for perfectionism. Are you not doing something that can be done easily, just because you feel that you don't have time to do it the "correct" way? Ultimately, you must choose between "doing it" (even if imperfectly) and "not doing it" (and waiting and waiting until you have the time). If this is a hard decision for you, your delays may be rooted in a need for perfection. Take it from me: The world won't end if you don't do things perfectly.
