It is not trivial to understand the necessary complexity of a problem. In SICP, there's an early practice problem that asks you to turn a recursive number pattern generator into an iterative generator. What the problem doesn't tell you is that the generator obscured by complex recursion is actually creating a tribbonaci number sequence. This hidden insight turns a difficult problem into a trivial problem.
