At some points you'll move from mistake vs correct play to finding imbalances. Most things aren't really mistakes but contain advantages and disadvantages. Matching all these imbalances together to a strategy and at the same time disturbing the opponent from putting his imbalances into synergies, that's what expert games are about (or at least higher advanced level, I can't say I really understand expert level).
