I think I've cracked the code. Just come to the beach. Bring your bucket and your shovel, a couple of big towels and your swimsuit. Oh, and don't forget some books. Nothing too cerebral, just easy beach reading. Leave clocks and watches back at the house. Tell your everyday life to hold its noise, you'll be back in a week.
First order of business is to walk along the beach. Even if it's late when you get there you can walk along the water's edge with the waves slapping your ankles....
.....and watch the sun go down, the best kind of multi tasking.
Get some sand between your toes and listen for the music to start in your head.
Wear something short so you don't have to get the hem of your britches soaked by a sneak attack from a runaway wave. Soon the pounding of the waves will blend with that music in your head and wash you over with peace and tranquility.
