K) Five Ways to Find Harmony with the Natural World Walk: Break the rhythm of permanently being under a roof. Get off a stop earlier, make a circuit of the park at lunchtime, walk the child to and from school, get a dog, feel yourself moving in moving air, look, listen, absorb.

　　Sit: Take a moment, every now and then, to be still in an open space. In the garden, anywhere that's not in the office, anywhere out of the house, away from the routine. Sit under a tree, look at water, feel refreshed, ever so slightly renewed.

　　Drink: The best way to enjoy the natural world is by oneself; the second best way is in company. Take a drink outside with a good person, a good gathering: talk with the sun and the wind with bird-song for background.

　　Learn: Expand your boundaries. Leam five species of bird, five butterflies, five trees, five bird songs. That way, you see and hear more: and your mind responds gratefully to the greater amount of wildness in your life.

　　Travel: The places you always wanted to visit: by the seaside, in the country, in the hills. Take a week-end break, a day-trip, get out these and do it: for the scenery, for the way through the woods, for the birds, for the bees. Go somewhere special and bring specialness home. It lasts forever, after all.
