1. Don't go without a hook file. EVER!
2. Any question about the leader? Change it.
3. Do you feel like you are going to catch a fish with your next cast? If you don't, you are right. Move or change tactics so you can be confident.
4. Always have a net in the boat big enough for the biggest fish in the river.
5. Somebody helped you learn how to catch fish. Make a point of sharing that knowledge with someone else at least once every day on the river.
6. Whenever possible, avoid return deadlines. If I tell my wife I'll be back when the fish stop biting", she knows it will be after dark.
7. A good fishing buddy is difficult to find. Learn to recognize the good ones and don't screw up the relationship.
