“I get nervous before big games and I cannot sleep.”

Nerves mean your body cares. They are not proof that you are weak. The problem is when you treat nerves like an enemy. Then your brain starts fighting your own body. Now you are tired before the game even starts. The night before, write down your first three jobs for the game. Box out. Sprint the floor. Take open shots. Then stop thinking about the whole game. When you get in bed, breathe in for four seconds and out for six. Long exhale. Again and again. That tells your body it is safe. You do not need to feel calm to play well. You need to know what to do when the energy shows up.
