The Fischer quote sounds like the opposite of what you're saying, i.e. it's a suggestion to prioritise macro over micro: "from good logistics, tactics will sort itself out".

You could read it both ways. I would say tactical opportunities flow from a better position. If you're a good enough player that exploiting your tactical opportunities is automatic - and this doesn't apply even to most grandmasters - then you can afford to spend all your energies on creating those opportunities. If you're not good enough, creating strategically better positions is of limited value.
