the average I believe is 7 items in short term memory.
any more (like for a shopping list) write it down.
or repeat it to yourself by saying it 10-20 times out loud. writing it down usually helps too because that aids for some ppl in memorization.

Ain't no way I'm gonna remember seven whole things in my brain all at once.

I'll remember 7, but if I need to get to the store, that's one, if I'm driving and I get irked, that's another. By the time I get to the store, my list is milk, get to the store, that red light was too long, why can't bmw drivers use their turn signal, I need to clip my fingernails, and what do I want for lunch?
