Yeah, and I think that a cause of procrastinating is the idea that as soon as you start on something your time will be occupied for the next few hours/days/whatever by it and therefore you will not start, because you have other things to do too and you feel you need to first plan out the expected time you need for the thing you want to start, and then procrastination starts. It doesn't have to be, if you start on something you can stop anytime you want and start later again by only surviving the first 2 seconds. You can do this as many times as you want. This way you don't feel something will take over your life and needs planning and you are able to do other things too, etc.
