AP (stamina) is your most valuable resource. Prioritize spending it on daily Commissions and Bounties first. After that, focus on Hard Mode stages for student shards of characters you want to upgrade, or Main Story stages for equipment materials you currently need. Avoid letting your AP cap out. Use AP potions strategically during events or when you need a specific material quickly. Don't be afraid to refresh AP with Pyroxene a few times daily if you're actively farming.
