Certain things I try and hammer into him.
Always make sure he is polite uses manners.
Try and encourage him not to give up when something his hard.
Teach him to be 'handy', how to fix his bike or do little repair jobs, he still a bit young to teach properly but nothing worse than a grown man who is completely useless.
Don't allow him to have teddies, wear gay animal "onesies" or dressing gowns and shit, only allow not feminised toys.
Make sure he always respects and looks out for his mother and sister.
Couldn't stand it if he ended up like a lot of the little bastards you see these days
