That's kind of my point. I didn't need to be "at my best" at those times. When I really need to figure something out at work, I do my best to eliminate distractions as much as possible so I can be "at my best" (I work in an open office). But even that's not needed 100% of the time. Sometimes you're just doing grunt work that needs to get done, sometimes you're doing something you've done thirty times before. But sometimes you're figuring out one of the trickiest interlocking puzzle you've ever come across, and that's when I need to be at my best.
