A lot of what feels like laziness is just not knowing the very next step. Make the step smaller.

Avoidance usually means the task is undefined rather than that you are short on willpower. A vague instruction gives the mind nothing to grip, so it goes somewhere with clearer feedback instead. Calling that laziness adds shame to what was really a planning problem.

Take the thing you are avoiding and write down the very next physical action, small enough to be slightly embarrassing. Open the document. Find the phone number. Once the first step is obvious, the resistance usually turns out to have been attached to the fog rather than the work.
