Get a Blunt Read on Whether Your Excuse Actually Holds Up

You have a perfectly reasonable sounding explanation for why {THING} has not happened yet, and some part of you does not quite believe it either. This tells you straight whether it holds up, and if it does not, names the real reason underneath it in one sentence, no softening included.

I keep telling myself this reason for not doing {THING}: [state the excuse or reason as you actually think it]. Tell me plainly whether that reason holds up or whether it is a polished way of avoiding the thing, and if it is an excuse, name the actual reason underneath it in one sentence. No encouragement, no softening, under 80 words.
