The biggest difference (for you) between you and other people is that you are on the inside and they are on the outside. This difference dwarfs all other differences, and you (like everyone else) are not capable of evaluating yourself compared to others as a result.

p.p.s. OT: any reason my kitten should be stealing the sponges from the sink and worms from the ground, and carting them around?
