I think it's mostly about accepting that you are the one in control. The problem of "getting yourself to do something" is poorly formulated, as though some other person was in charge of your actions that you have to convince to do what you want.
This confused conviction is the real problem. There is no other you to convince. The same you that you are bargaining with to do the thing is the same you that's doing the bargaining. You can at any moment just do it.
That's really nice but not really true. There is another you that you need to convince to do boring stuff. That's our own body fighting against doing that stuff. Will is a finite resource.
