I thought much of organic chemistry was very intuitive when viewed from the perspective that there are nucleophiles and electrophiles and they attract. That was my generalization. It's certainly not a complete point of view (particularly for pericyclics) but it did me well through the courses I took involving organic. And resonance, understand resonance.
I too am on the physical side of things and you'll see as you go on the universe is not orderly and tidey. Only the simplest systems (virtually noninteracting) can be handled exactly or even near exactly.
