I'm having a problem where I've challenged myself so much in little ways and built myself up so far, that in order to improve past this point, I see extremely huge frightening tasks in my future. Past the point of discomfort, I am looking at staggering terror ahead. (I wish I could elaborate, but unfortunately I have to keep my current situation to myself.) I guess in terms of public speaking, it would be the equivalent of addressing an audience of a million, as opposed to a hundred.
