Let it swing

The fishing has been tough. You step into a run and it is time to pick out a fly. The last 5 runs you fished, nothing worked. Big, small, loud, subtle, didn't matter; nothing worked. You grab the nicest one in the box that you tied; then you put it back. No way are you going to toss that fly in this run because if it doesn't catch a fish, you will have just blown your ace.

However, you realize that all you can do is fish the run to the best of your ability with that killer bug. Life is good. It is what you make of it. So be the best you can be, fish as well as you can and be happy with it.
