Why are women obsessed with a man's height even though it cannot be changed?

I'm a guy who is between 5'6 and 5'7. I'm seeing that majority of the women are not interested. What should a short guy do in order to be the best possible person of himself. I do like working out and have abs but still I feel it doesn't matter to women compared to height. What are your suggestions?
