I came within an inch of graduating with an A overall, Fubbo, i averaged 4th in the standard (ie grade) for half of highschool, and I've never been a success. Don't let it bother you.
Life is what you make of it. Find your passion. Do what you love -- then you'll never work a day in your life. I'm only now discovering what i might like to do with my life, and i'm 31.
Also, what fifth said :P
