I don't think you should look for anything. You just meet people as life goes on, some you get the stomach lurch, some you don't. That's how I live life.
Over the years i've learnt not to look for things in people, i'll always be disappointed. Also, I don't date, I just want lots of friends. That will be hard for me, because when they enter in a relationship, they won't be able to hang out with me anymore.
I have qualities I like in people, but it's not really essential if they have them or not. I could fall for the complete opposite.
