I've never taken a calculus class and I'm very productive in Haskell. Maybe knowing all of the applied Math and that there is a better solution available in Haskell keeps you from being productive? I take the route of solving problems the first (or second) way I come up with, then take advantage of how easy it is to refactor Haskell code when I have a better solution later. For instance I didn't understand Monads too well while writing my first Haskell program and just did everything in continuation passing style.
