Throughout the course of a day it's possible for me to have moments of perfect confidence as well as moments of incredible self-doubt... and everything in between. Feeling more confident more often would probably be good, but I think my at times high levels of self-scrutiny allow me to much better make use of every day as an opportunity for personal growth. And if personal growth is done right, it should lead to more feelings of confidence, so on average it tends to for me be a slow upwards rise (very slow, think years, not weeks) - only affected by major unexpected events. So if things keep up the way they've been going, by the time I'm 90 years old I'm going to be an annoying overly confident knowitall.
