No, I wasn't implying that that was your only motivation. To be happy with how you look is a very good motivation IMO. I'm just very skeptical of this whole alpha and beta theory, because there really is no scientific proof that is applies to humans and I don't think humans can be so easily divided into these 2 categories, I think human relations are a lot more complex than that.
Stop say human, you make it seem like we are different from the animals. There is no difference. So alpha and beta obviously exists today. Just in more finer places it's more subtle than in the slums. but i "dare" you to enter any of the violent Iraqi,islam zones in scandinavia or the black neighourhoods, You would figure out the hierarky in any of those social settings rather quick. Same goes for prison to put it more obvious.
80% are straight to beta. Then the other 15% think they are Alpha but they are generally the right hand of the true Alpha. And the remaining 5% Are the pioners/creative/tall(bigger than life)Cartoon characters in real life & lifestyle kind of people.
People we generally look up too like. Arnold, Sly...or your local youtube celeb these days.
If you are short you are doomed to betaness. Whether you like it or not. Now your degree of betaness can be off different levels ofcourse. I would say that the majority of cases where the Short guy is not bullied is when he has a masculine aura AND a good social network with "permanent" ties which makes him valuable to everyone else. But as soon as he looses that "thing" he is back to square one and will notice withdrawl of social progress.
