nobody is average, everyone has something unique! trust me boy, you do have something hidden in your personality. to change the looks, jeans and t.shirts are cool, you can try to wear shirts sometimes, fix your hair when you go out, smell good, have a smile on your face.
but honestly, you dun need to change yourself just because of people will like you if u'll be hot. Nothing is hotter than a man himself. the way he talks, walks, attitude, personality, it all depends on each individuals!
