Re-thinking task management systems for my ADHD brain!

The best task management system does not equal productivity. All my life when I struggled with completing tasks, I was told "All you need is a good task management system! That will help you get things done". I started to believe that and now trying to work with my ADHD brain, I realize that task management systems is just that... a system that tracks your tasks. A good task management system needs these three basic things. 1.) Does it track your tasks? 2. Does it track when those tasks are due? And last, is it easy to access where ever you are. If your system does at least those three things, you have a good system. So now the real question is, what is going to make you do those tasks in your system?
