Average is comfortable, people don’t want to stand out from the crowd and be noticed. Having the ‘wrong’ height, build, or even dress sense makes people feel uneasy about who they are. True some organisations go out of their way to recruit people that ‘don’t stand out’, but that concept of average stops at the physical presence of a person. Is average really a good thing to be? Well, average weight for height is possibly medically sound, but in almost all other things being yourself is far more important than striving for some artificial norm. Everyone has something to offer to humanity.
But thinking yourself to be average and thereby stifling your potential is the bigger crime than a desire to conform.
