I feel you on this. I have found that no system lasts for me. I have also found that any system can help to get me going. Such that now I try not to use anything to plan his things will end, but only how I will begin them.

Similar problems hit me with exercise. About the only system I have there is too obligate myself to finish something. For example, if I walk the dog a mile out, I have to walk the mile in, as well. Bike to work? I have to bike home now.
