If you're average, then there are a lot of coders who are objectively less skilled than you, by any reasonable metric. Being humble doesn't require you to claim otherwise.

I'm not being humble, or trying to be (or trying to appear to be). That's how I really feel. I suck. I'm not average, either. I actually think I'm the worst guy in the room. How come? It helps me prevail over any obstacle. By understanding that I suck, any problem that makes me stumble is not too small for me to tackle. Doesn't matter your skills or experience, everyone always hits bumps.
