Just curious to see, some poeple pick a spot and work it hard, while others hit and run if there is no actions. What is your philosophy:question:
I have always heard, and subsequently practice, the 15 minute rule. If no bite for 15 minutes, move. The fish are either there or not. That being said, I work that apot hard for that 15 minutes. Unless it is an area that you know will produce. There are some spots that are known to produce and it is also known that the fish “migrate” through an area. Those areas I will give more time to. By working it hard, I mean several baits in the water. I usually have a live shrimp on the bottom, a piece of cut bait the bottom, a live shrimp on a cork and maybe working a soft plastic of some sort. Let the rod holder fish the baits while you work the soft plastic. If one of the baited rods goes off, you know what is the preferred menu of the day and the technique that is producing. Regardless of what is going on, I always try have a live bait and a piece of cut bait on the bottmom on a Caroina rig. Some days only live shrimp will produce. Then some days mullet/croaker/pinfish/menhaden/mud-minnow work best. Always best to have a variety in the baitwell. Just don’t mix mud-minnows and live shrimp. The MM’s will eat the eyes off, and kill the shrimp.

Croaker and pinfish will also eat your live shrimp.

I agree with TexasRed but will usually work a spot a bit longer, like 20+ minutes. It depends largely on whether I’m fishing for fun or “work.” As a charter captain, the only “work” is cleaning the boat, in my opinion. 
When guiding clients, you are in a unique situation, and have to strike a balance between finding action and letting action come to you. You can’t catch fish without a wet line, and if you spend more time bouncing from spot to spot and less time fishing, you might actually decrease your odds. It’s a balance that changes based on lots of factors (conditions, tide, past location history, baits, and of course patience.)
Sometimes you can fish a spot for a few days in a row, knowing the fish will appear, and you’re better early than late. I can’t tell you how many times we’ve decided to work a spot “just 5 more minutes” and seen action, when it was dead for the first 15 or 20 minutes.
In fact, the “just 5 more minutes” strategy is a good indicator that you have a true fishing addiction, and the only cure for that is more fishing.
