Discouragement is not the absence of adequacy but the absence of courage.
Way back in the day, when I first started and had delusions of adequacy as a cartoonist, I would listen to music. When I switched to a career as a writer, I would try to listen to music, but if the songs had lyrics they would get in the way of the words I was trying to write. So I switched to listening to purely instrumental pieces.
Life is supplied with a basic adequacy.
He had delusions of adequacy.
Adequacy is sufficient.
