I think I am average looking so far as I can tell. I have no real issues of self-esteem, I simply recognise my limitations; too few people do that.
However, that has nothing to do with Iago; do you feel sympathy or empathy for his character?
That's a negative, the only limitations are the mental one's. For instance, let's use Mercedes Benz's Amg cars. Merc has a electronic govenor on it's cars set for 155 mph, but for a small fee, they can lift that for that the car does 186 mph. But they admit, that the cars will do 200 + mph, flat out, the only limitations are the HP and the weight.
Merc's limitations on the cars MPH limit's represent you mind limitations on not just your body, but growth as a whole, as a person. Remove said, limitations, and you'll see growth that you haven't seen before. Think about this, when a person is hypnotized, they can lift or do things that they couldn't consciously do, so what is that saying about the mind limitations and untapped potential.
Now, as far as the Iago, i neither feel sym or eymph for him.
