If it works for you, do you. Everyone's different. However, being the way you are right now came back to bite me in the ass at one point in my life.
I used to be judgmental and look down on people too, which was easy for me because - like you - I realistically have a lot going for me. At some point, I realized I wasn't being strong - I was being a weak little boy.
Being an alpha male isn't just about being mean and aggressive (sorry puaninja but I'm gonna disagree with you here). Truly strong men are generous; open; warm. Do you think a real alpha male is going to be rude to other people? A real alpha has NOTHING TO PROVE, and trying to dominate people he doesn't know through RUDENESS, BEING DISMISSIVE etc is NOT ALPHA BEHAVIOR.
It sounds like you might have some inner issues or insecurities - and most likely aren't fully aware of them yet. You might read this and think "damn, this guy is an idiot," but if you made this post you probably feel like something's wrong on some level. Somewhere deep inside, a small part of you doesn't like the way you're living right now.
You can handle your problem now or you can wait for it to spiral out of control and fuck you HARD later down the line. Listen to what "poeticlyskuac" said - read up on meditation, read some Eckhart Tolle, compliment people, etc...
Trust me bro, the light side of the force is infinitely more powerful than the dark side
