Race against your own tendency to delay.

Delay is rarely about the task and usually about the moment of starting, which is uncomfortable in a way that nothing after it is. Treating it as an opponent rather than a personality trait makes it manageable, because opponents can be studied and beaten in small ways.

Time the gap between deciding to do something and beginning it. Try to shorten it slightly. You are not trying to eliminate reluctance, only to stop it from being the thing that decides.
