Think about school. Imagine that having to go to school interferes with your fun. If you only go to the beach, then you fail at school. If you only do schoolwork, you get very tired and bored.
Work/life balance is about doing some school and some fun, so that you can manage a bit of each, and don't fail at school or get too tired to have fun.
So now write a bit about how you combine the two, and in what combinations, to have the best possible life without one part suffering too much.
