4. Billy Corgan
Billy Corgan is the lead singer of Smashing Pumpkins. Billy has a very rare mark or Klippel-Trenauney syndrome on his palm and fingers which he has since birth. The mark doesn’t make him unfit for any physical activity but the scar is prominent in his hand gestures however his performance with guitar has never been effected by this mark. This is how you own any flaw your body has with confidence.
