I cannot agree with purists who say get it all right in the first shot...it doesn't really happen.

Completely agree - I kinda chuckle when I hear that.

Pretty much the same as everyone here - came from film (4x5 and multiple medium format sizes, as well as 35) and when I switched I shot more for the candid stuff because I could just delete it later. For the studio, I set everything up first and know what's gonna happen when I hit the shutter, but there's STILL gonna be a few, to several, exposures to get it (contrast ratio, exposure, slightly off-comp I didn't notice in the VF) right for me to further in PS - yes, I cheat with every shot!

Yeah, there's just more freedom to experiment knowing I can just hit "Delete".

If you wanna go back to the notion of film, take small cards with you, and no way to transfer to larger storage and refresh the card - say, maybe 256MB cards? that would creep you into being more careful about firing the shutter!
