I'm really a scientist. I follow recipes exactly - until I decide not to. And then I'll follow something else exactly. I may decide I could turn this peach tart into a plum tart, but if I'm following a recipe, I follow it exactly.
I just found out last week - my sister told me - that my father had some Beatles records. So I must have heard them quite a bit, but it never registered, really. Now I listen to them with new ears.
