Be honest about “can’t” and “won’t.” Half your can’ts are won’ts wearing a costume.

There is a real difference between impossible and unwilling, and blurring it mostly fools you. Saying you cannot do something makes it sound settled and external, when often the true sentence is that you have decided not to pay what it costs. Genuine limits exist too, and those are worth naming clearly, so you stop spending effort where there is none to spend.

Take three of your current cannots and rewrite them as will nots. Notice which ones you are comfortable keeping. The ones that suddenly feel wrong are worth another look.
