Think Rolls of Film.

In Scott Kelby's book "Crush the Composition" he wrote "'Then they start working the scene that’s in front of them and maybe that means taking 20 shots, or maybe that means taking 100, but they keep doing it until they can look at the back of the camera and say, “Nailed it!” Only then do they move on to the next scene or location and start the process of seeing and experimenting all over again."

Of course film is your card or cards in your digital camera.

Back in the day you had 24/36, or less, rolls of film. When you worked the scene did you need to actually take photos, wait for the processing and then review the negatives to select those to print?

Now in fast paced action, or perhaps street photography, burst shooting has it's place. But when you're working the scene do you need to take 20 or more shots? Maybe not. Slow down, use your eye, viewfinder, to visualize the photo.

Yes I often take many photos at an event because I'm looking for those that are unique. The candid shot with the unique expression. The those without the pasted on smile or expression.

Of course YMMV.
