“Under the water there, that’s the real you. The waves are always going to come crashing in—sometimes in ways that are fun, and sometimes in ways that aren’t. It’s just like at the beach. Those waves are going to keep on rolling in toward the shore. But you have a choice: You don’t have to have your inner calm self tossed around by waves of fear or sadness. The core you is that quiet place within yourself, and you can go there any time you want, whether you’re happy or sad.”
