My goal is to progress from one psychological stepping-stone to the next throughout the course of my life; the journey will never end, because perfection is subjective. (Each stepping stone, in truth, is an analogy for confidence: a "progression from one stepping-stone to the next" is the changing of a belief into knowledge.)
I fail every time I try to advance from one frame of mind to the next, because what I am really doing is projecting false confidence in order to will it within myself.
And then in cases when I feel like I have grown in some knowledge, the success was due to what I learned from the failure. (To make the analogy more literal, it's like falling off one stone as I try to get to the next... and then I have to get back on the first stone again and learn how to do it right.)
I fail when I act on behalf of myself. The answer never has to do with me.
