confidence?

Sometimes, I am not sure if being confident is a good thing.
Confidence means you know you are better than others, you know you are superior, you know you will do well.
Or at least you tend to believe and have faith in yourself.
Hence, the expectations.
However,
with high expectations, the disappointment you need to endure after you fall hard on your face,
is just…..
unbearable.

tell me,

should one really be confident?
