If you can, at least once in your life, punch Poseidon.
When the tide is tall and choppy, curling into water cliffs, charge into the waves. They'll pummel you with salty fists. Stand against them at first. They will start thrashing you. Let them. Let them sweep and scrape you across the shore. Dig your hands and feet into the sand. Be seaweed, rooted down, swaying with the current. Let the foaming mouth swallow and spew you out. Then, when it thinks it's quelled you, run at the waves again. Crash in. Tangle. Switch between boxing with the water and dancing with it. Seize the frothing joy.
The ocean will learn it can move you, but can't claim you. You both belong to yourselves, and will always battle it out or carry each other. You'll return to each other in tides.
