I think I have to disagree with this one. A major part of being an effective programmer is the ability to maintain state and call stacks in your head. Stepping through code is great - as a last resort. But I've found that if I need to run through it with a debugger in order to understand it, it is often overly complex. As with any generalized rule there are exceptions, but I consider needing to step through code in a debugger to understand its behavior as that exception, not the inverse.
