Paddle slowly. Simplify.
Kick off the fluff. Listen. Wait. Look. Remember.
Then, think.
Stay an unpredictable length of time. Don’t try to do anything except to notice what is happening. Mostly it is not complicated, but stillness and patience seem to be a pretty good starting posture. The water is the most vital item except maybe in the dead of winter.
Go barefoot. Stoke the sauna. Swim naked.
