What do you think is the single biggest mistake that a beginner makes in the quest to catch that first steelhead?
I'm kind of prone to thinking it's "blind casting"....just aimlessly tossing the offering hour after hour. I know there have been times when I've fallen into that mental state. It doesn't happen often, but occasionally when the fishing is slow, I'll lose my concentration and just drone it. What a waste of time that is! Sometimes I need to kick myself in the butt and change lures, or holes, or both....got to stay dialed in!

What single piece of advice can be offered to help a beginner?
