1. Turn all care out of your head as soon as you mount the chaise. 2. Do not think about frugality: your health is worth more than it can cost. 3. Do not continue any day's journey to fatigue. 4. Take now and then a day's rest. 5. Get a smart seasickness if you can. 6. Cast away all anxiety, and keep your mind easy. This last direction is the principal; with an unquiet mind neither exercise, nor diet, nor physic can be of much use.
