Hello @grosgood
@Silvio_Grosso has shot — what, ten million?
Milion not, but thousands is quite likely 
Just to give you an example of a “single” session of a working day:
I always try hard to take only one very best shot per sample in order to reduce the amount of fixing up later (with RawTherapee and GIMP). For instance, I always use a tripod, the lowest amount of ISO etc etc
A former colleague of mine, now retired, told me that “a good photographer must try to learn how to shoot the least amount of pictures per day”.
Usually beginners take a lot of pictures because they are not sure about the final results (and usually have plenty of time to fix them later on…).
