I agree with MysticMystic said:
You can't make people do anything. In fact if you were to try and force him to be athletic and sociable you may push him away and make him resent you. Then he won't listen to a damn word you say.
It is ridiculous to think that you can "make" your son a DJ. The best you can do is to guide him and show him, but hope that he takes matters into his own hands. Your job is to surround him with experiences that will allow him to grow.
That being said, I think the best thing you can do is lead a DJ lifestyle yourself. He will naturally try to emulate you and will pick up your habits as he grows.
Try to have activities on the weekends where he can see you socializing. If you have a wife, use her to show him how to treat a girl (without grossing him out obviously). Be athletic or if your unable to do that because of your health, become interested in the sport he plays and allow him to feel like you are proud of what he accomplishes athletically.
Diet! that includes yours. IF your family only has healthy food around the house and he watches you make the right decisions. He will be more likely to do these things himself
You can lead a horse to water, but you can't make him drink. This is not a dog that will follow you blindly and loyally, its a human with a will of its own. That being said, just because you do these things doesn't mean your son will come out a DJ. Like pen kitten and others said, his personality and environment you can't control will make him the person he becomes. What i mean by that is you cannot control it if kids at school make fun of him for x reason or if he is able to eat a poor diet away from home. You can try to intervene, but in the end he will have to either sink or swim in the real world because you can't watch him 24/7.
