Confidence is a funny thing. The idea of knowing one’s self, and believing in one’s self, is universally considered to be a good thing. Whenever there is a shortage of confidence, the prescribed solution often reads like a family recipe: just add more confidence! Whether it’s a facade or genuine, more confidence will cure what ails you!
Until you overcorrect, and that extra ounce of confidence turns the whole thing into hubris, and all of a sudden you’re overextended, as if you’re hurtling down a snowy hill on skis and you need to use all of your energy to try and slow your momentum.
