If you were truly OCD like a friend of mine you would do what he does and skip every other frame as you shoot.
"Film is cheap." I've been known to shoot three frames of shots I think I'll really like. Some people bracket exposures but I rather take three at the setting I believe to be correct. That way I end up with a frame to print that isn't on the end in a strip of five. Plus, it gives me a backup in case the first one gets damaged somehow.
