The difference between a good guide and a great guide: The good guide can get clients into a lot of fish; the great guide can get clients into a lot of fish, no matter the challenge.

Rusty is one of the greatest guides ever. Case in point, the day he was fishing with his client Jim. Now, Jim is a great angler, been fishing all his life. But, sadly, Jim now has Parkinson’s disease. His casting arm shakes badly, so much so that he wiggles his flies, making them unappetizing, even for the most aggressive trout. On this day, however, Rusty made one simple suggestion, and Jim caught a dozen big ones.

What was the suggestion?
