I have come to the conclusion that my previous effort to implement GTD, while not a total failure, has been fraught with problems.
One thing I have noticed, I sleep better when I have things planned, taken care of, or documented. I have not been sleeping as well for the last couple of weeks. Guess what? I have been depending on my brain to keep track of todos and concerns. Those of you that know me know that this is a plan that is doomed to fail.
I will be re-reading "Getting Things Done" and "Time Management for System Administrators" to help me get back in the groove of things.
