How many pictures is enough in a day?

If I take a picture and there is something wrong, I delete it. If I just plain don't like it or it's too similar to other ones that are better, I'll delete it. Generally, because I delete as I go, I'll end up with 20-50 a day depending on what I'm doing. For example, I was in Italy at the start of summer and came home with less than 150 pictures in two weeks, but all of them were at least decent or had potential in post processing

Just do as Sebastiao Salgado, fill 200 rolls of Tri-X on a trip and let your assistants sort through the pictures.

Some days I'll take hundreds of shots (even on film) 'in a day' just walking down the street, others I'll take two. I'm packing 10 rolls of Tri-x (Leica) and 10 rolls of Provia 100f (XPan) for a seven day trip with no plans to leave any un-shot.

It depends on so much, I would say enough is when you got the shot. If you ever get the chance to see some contact sheets of a famous photo, you'll notice the photography probably took any number of other photos of the same scene to get the one spectacular image.

Not knocking anyone here, but conserving 35mm is pointless. Trust me, when you start to waste or accidentally 4x5's, THEN you will feel bad!

I find that 12 is too much.
