how do I get smarter?

does /prog/ ever have learners' block?  I feel difficulty in grasping ``advanced'' concepts recently, like derivatives (dx), fractals, and some of the more advanced concepts in Haskell.

what do, /program/?

1) Go to khanacademy.org
2) learn at your own pace
3) Participate in project euler or read textbooks (ie e-books)
