Georg Simmel

The psychological basis of the metropolitan type of individuality consists in the intensification of nervous stimulation which results from the swift and uninterrupted change of outer and inner stimuli.

From a good lie in the middle of a fairway bunker, I'll make the same swing as I do from an average fairway lie. I'll dig my feet in slightly and keep my lower body stable so I won't slip, but I don't change my club selection or setup. It's only when the ball is sitting down in the sand that I'll make some modifications.
