I believe that the procrastination is closely related to the inner dictator/inner rebel polarity. The inner dictator is the voice that tells you what you should do.
Excercise,eat healthily. Get some work done. The inner rebel wants to do what feels good in the moment.
The trick is to see if these two tendencies can be reconciled. But it always implies a break from the present moment. Meaning, right now you are on Steemit, reading some article, the idea comes to your mind that you should get up and go for a walk. Now maybe the walk would be pleasant, but you need to get up from the chair first.
You can get into the habit of doing this. Sometimes the easiest is just to try top establish the habit, so you don't need to feel the active choice.
But no matter what you do, stop thinking that you should do anything.
You can sit in the chair till you rot.
If you want to.
