Hey I'm 14 years old and I'm danish so English isn't my main language. But it doesn't hold me back. I wanna be an iPhone developer. I learned to 3D model/map... when i was 12 years old and i made levels for PC games. So i think I'm able to learn the Objective-C language, and develop apps for the iPhone. But here is my issue (or not). I'm currently reading the "Programming in Objective-C" and I'm understanding it all, but sometimes i find myself reading the same line/s 2-3 times. But i usually understand it all... I feel really stupid asking this. Is it normal?!? I want to know because, my dad bought me the 99 dollar standard developer program. And he bought me a Macbook Pro. And I'm afraid that i don't learn it good. Sure everybody could learn it but there is a difference between learning it good and just learning it. I know this really sounds dumb, but i told my dad that this wasn't something stupid that i just wanned to do for 1 week. So I'm asking once again is it normal that i sometimes find myself reading the same line/s 2-3 times.
