Good on you for not caring about it! I didn't care about it until Grade 8 - then all of a sudden was extremely self-conscious, and it ruined my life - then I dragged myself out of that hole when I was 19 and slowly recovered. Don't do as I did, haha. Now at 28 I'm very proud of who I am, love myself, love my stutter, and I even think my stutter has helped me more than hurt me in life, in many ways. Keep going man. You've got big things to do and the stutter's not important.
