If you don't look before you jibe, there WILL be someone behind you. When you drop off your board to rest, the water will always be over your head. You always sail one meter too far when coming back to shore. 5c Sandbanks move at night. In shallow water, always sail behind Roger Waite.
Traffic lights are only red on the way to the beach.
No matter where you go, there you are. Do first what's due first on the job, and you'll have more time for sailing.
