Flat? What is this flat? What's wrong with standing on an edge and looking down at daylight?
If things don't tear you up now and then, you don't put enough stock in yourself. If you stop learning, you are on the short path to a bad ending. You can learn even from the greenest kid you'll ever meet. I know the % won't be right. But. Something like this, you will learn/retain around 30% of what you are taught, you will retain over 90% of what you teach. If you find yourself lacking somewhere, find both a stronger AND a weaker person in that area, to learn from by learning and by teaching.
I hope that make any kind of sense at all.
