You’ve done all your homework. In fact, you probably over-prepared.
But you still have your doubts. So you practice again to rebuild confidence.
As much as you plan, it can still go all wrong. Just look at Peyton Manning and the Broncos last Sunday.
Sometimes over-preparation and more information can backlash. You’re so worried about remembering everything and being perfect in practice that nothing comes out during the execution.
Hard work doesn’t guarantee success, it just strengthens positive habits to better prepare you for the right opportunity. Don’t overthink it when it matters, just play the game as you best see it in your mind. You’ve already done all this before.
