You at your worst and you at your best are right next to each other.

You'll think you're still in your best zone and actually you've shaded into your hidden worst case.

The part where you're not creating value but you think you are.

Realizing that you are not creating value, or that you're destroying value, will be even harder.

Because it will be intertwined with your ego.

"No, no, I can't be doing a bad job here because a defining characteristic of what makes me good is this skill."
