Is It OK to Have an Occasional Banana?

I look at bananas the same way I look at a dessert, like ice cream or a piece of cake. You don't want to eat a ton of bananas, but it's okay to have the occasional banana for yourself. The next question is from Liam, who is a nine year old warrior kid. He says, how can I keep my mind on doing warrior kid stuff? And one of the ways that you get good at focusing is by pushing yourself.
