Recursion is fairly straightforward once you have done it a few times. My suggestion -- try writing a few recursive function. start with Fibonacci.
Essentially you break your problem into sub problems until you hit a really easy sub problem you know the answer to. then you use the sub problems to solve a harder problem.
