Do you have a healthy self esteem?

I’m getting really down on myself today because I received a poor grade on one of the three tests I had last Friday. I know I should be more forgiving of myself since it is only a minor setback, but because it was an error of carelessness that caused the grade I can’t help but be pissed off at myself. And I’ve been thinking, I get pissed off at myself for these kinds of things a lot. And the constant mental self-flagellation prevents me from solving the problem that caused it to begin with so I’m stuck in this positive feedback loop where I exacerbate my anger by creating more problems.

So I’d like to know, are you the same way, or do you have sufficient self esteem that you can make a mistake without beating yourself up about it? Are you self-confident or are you always second guessing yourself? How does your level of self esteem factor into your everyday life? Answer this question however you’d like, these are just examples of things for you to consider.
