Do I have the potential to accomplish this "HUGE" goal? *10 Points**?

I am currently in 8th grade. 4th to 7th grade, I always earned B's C'd coupled D's due to my negligence of paying attention. I have A.D.H.D, which I consider a gift. My I.Q. is 130, which is beyond average. However, I am far behind in knowledge. For the first quarter in 8th grade, I received A's B's and C's. I started to have a different perspective in life, so I started working extremely hard. I reed alot of books such as World history encyclopedia, psychology, math, economics. Some times I reed too much, I burn my self out. Yes I have been devoting time for fitness, but my mane focus is to p other kids in knowledge. This next report I have earned almost all A's. So my "huge" goal is to become valedictorian. If I keep working hard reeding extra curicular, GPA, etc. will I succeed?
