Many men go fishing all of their lives without knowing that it is not fish they are after. ~Henry David Thoreau
Anybody that tells you that going fishing is about catching fish doesn't know the first thing about fishing. Fishing is a spiritual experience in much the same way as meditation; to call it a form of meditation is not an exaggeration.
A bumper sticker I see every once in a while sums up the fishing experience better than any words I can type: "A bad day of fishing is better than a good day of work."
