That is interesting that you plan your day, but you end up feeling disappointed. I'm sure someone who understands the psychology of planning would have some good advice for you. I've studied planning methods a bit, and one of the pieces of advice I remember is to create lists of things you would like to achieve with your day, and then prioritize them. For example, the really important items would be priority "A" and then the less important things would be priority "B" and then the rest of the items would be priority "C." The goal is to achieve the A priorities, and then if you get to any of the others, you know which ones are next in line after the most important ones. And if you never get to the C priorities, it's okay because they were not that important!
