Hi, When I was in elementary school and high school, math class was very fun and easy and I was naturally good at it. But then when I turned sixteen I had to stop going to school and start working. I had no other choice. A devastating head injury on the job made me unable to work. Now, at the age of 25 I have nothing to do, and so I was thinking of starting mathematics again and perhaps one day if I get really good at it, I might be able to discover new theories etc. Who knows. I bought the book "Mathematics: From the Birth of Numbers" (by Gullberg) and I will be studying it in 2012. Basically, my question is, how difficult is mathematics compared to the math one learns in high school, and also, can almost anyone get really good at it? Thanks.
