Eighty Percent

Eighty percent is good for my psyche. If I'm better, faster, stronger, smarter then 80% of people I would be just fine. Why? Because 80% is enough to be proud of, but at the same time not enough to be cocky about. Why? Because you're better off than 4 out of 5. So you know someone who is better off than you which keeps your ego in check but at the same time it gives your something to strive for.
