If you like what you like, go for what you like and don't settle. That's the whole DJ theme, isn't it? I am not a big fan of wasting someone's time for your own selfish gain, whatever it may be. Karma is a beeeoch and will definitely catch up to you. If you don't like these said 3-5 then leave them alone. Someone out there may think they are 6-7, maybe even 8-10.
But don't get mad when someone rejects you based on what you may look like. DJ skills can only get you so far. If a chick isn't attracted to you, she isn't attracted to you.
I don't think it should be that way though. Yes, looks may bring you in, but substances keeps a person around. Alot of those 3-5 could be quite attractive if you got the time to know them. But if you just want to stick with you ideal of a 7, then by all means go for it. But don't just get a girlfriend to have one. If you are such a DJ, get your 7 and girlfriend her. Are you a 7 by the way?
It kills me that you guys talk about getting women out of your league. But I tend to believe that like attracts like. Its like I've got a job, my own car, my own money, attractive, etc. So I am looking for someone who has those things as well. I'm not going to do too much reaching until I've achieved that status myself.
