That's solid advise. Even on days that suck. Just sitting on the bank or in a boat looking at the water makes you a better fisherman.
Some days my desire to be comfortable wins over my desire to get any better at catching fish though. I generally dislike activities that require a lot of restrictive clothing.
It is 2015 for Christ sake, why do we have position maintaining trolling motors and detailed underwater imaging systems... but still lack a quiet, portable, and easily affordable blast furnace ?
