I have found out, that if you do less tasks a day, than you never have enough time for them. And when you have a lot of tasks, then surprisingly you have time for all of them. The secret of the paradox is that we actually have much more time than we tend to think we have. So we can "push" more and more tasks into our schedule, until we actually have the schedule full and when we really can't do more than we alreay do...
