Getting Things Done®. It is hard. Very hard. Getting Things Done®, or GTD®, as it is known, is a complex system. There are a lot of different concepts first to understand, processes to implement, and systems to maintain. If you only follow a partial GTD® plan, then you do get some benefits, but you will never fully realize the real potential of the system. You know what it can do for you, and you want that. It is just that it is out of reach.
