I find that the three truly great times for thinking thoughts are when I am standing in the shower, sitting on the john, or walking. And the greatest of these, by far, is walking.

Every walk of life falls under the Testicular Imperative: Either you have the world by them, or it has you.

I do what I do instinctively, and that’s me. If you like me, that’s fine; if you don’t like me then don’t watch me.

Freed from the pressure of haste, the tyranny of film, and now the restraint of clothes, I found myself looking more closely at what went on around me.

Even in these mercifully emancipated decades, many people still seem quite seriously alarmed at the prospect of sleeping away from officially consecrated campsites, with no more equipment than they can carry on their backs. When pressed, they babble about snakes or bears or even, by God, bandits. But the real barrier, I'm sure, is the unknown.

There there is nothing like a wilderness journey for rekindling the fires of life. Simplicity is part of it. Cutting the cackle. Transportation reduced to leg - or arm - power, eating irons to one spoon. Such simplicity, together with sweat and silence, amplify the rhythms of any long journey, especially through unknown, untattered territory. And in the end such a journey can restore an understanding of how insignificant you are -- and thereby set you free.

It is always there, of course, when you come back from the green world. You have been living by sunrise and sunset, by wind and rain, surrounded by the ebb and flow of lives that respond only to such simple, rhythmic elements. But now the tone and tempo of the days switch. Instead of harmony, jangle.
