With attention deficit disorder comes hyperfocus. At least for me. When engaged properly this can be a powerful tool for productivity.
Fairly recently I realized that it is also a way for my overactive mind to let out some of that extra mental energy. Which in turn helps my mood. This isn't only a productivity asset but a necessary outlet for me. Writing is a hyperfocus activity for me, and I'm feeling the positive impact on my mood since writing daily for national novel writing month.
