If I'm playing in the morning I'll get some carbs early: porridge with chopped banana. If I'm playing in the afternoon I'll start with less carbs and have some eggs and fruit for breakfast then a light lunch about 90 minutes before I play so I don't feel sluggish or full.
Dad worked in a warehouse when I was little and I didn't see him for three years as he was doing all the overtime God gave him to buy me new ballet shoes or a new tutu.
