Some days are a measuring stick for how good you are. Most of us are not as good as we think we are, but a small number of us are much better than we may think.
Don’t let the realization that you’re not as good as you believe be something that discourages you. It should be the rocket fuel that boosts you to the next level of excellence. Let the rubber-meets-the-road moments humble you, but quietly humble you. No screaming outbursts because you’re sure everyone else can’t be that much better, but a quiet realization that you’re calibration was a bit off and you’ve got work to do.
