Being married to one type of gear. Just because a red corky and green yarn put a fish on the bank last week doesn't mean it's the ticket today. If I'm floating eggs I cast until I've covered all the holding water once. I then squirt shrimp oil on the eggs and work the water again. Then it's sand shrimp time. If bait doesn't do it I run a jig or a pink worm thru it's paces. If nothing has happened I grab my drift rod and chuck a spoon or spinner. If no fish liked the menu options then I move up or down river to another run.
Have the patience to work each run thoroughly and be flexible in your offerings.
