Walking is one of the finest exercises and a brilliant stress reliever and mood booster. A good walk can put the world in perspective and soothe your frayed nerves. If you really want to feel alive, go for a walk in the wind or rain!
Set aside 15 minutes (or more) to amble about outdoors. You don't have to go anywhere special. A walk around your neighbourhood, taken in an open frame of mind, can be just as interesting as a hike through the mountains. The purpose of the walk is to notice and savour any attractive objects or positive internal experiences, slowly, one after another, using all your senses - sight, smell, sound, touch, maybe even taste.
The goal is not to "try" to enjoy yourself or to make anything happen. There's no need to rush anywhere. Just allow yourself to notice, be drawn into, linger with, and then let go of whatever gives you pleasure - whatever calls to you.
How many beautiful, attractive, or inspiring things do you notice while you're walking? Do you enjoy the scent of pine, the warm sun, a beautiful leaf, the shape of a stone, a smiling face, the song of a bird or the feeling of the earth under your feet?
See if it is possible to be open to all your senses: the aroma of freshly cut grass, the mustiness of winter leaves or, perhaps, the smell of exhaust fumes and fast food; see if you can feel the breeze on your face or the rain on your head or hands; listen to the air as it moves; see how the patterns of light and shade can shift unexpectedly. Feel the texture of a stick if you like.
Try stopping and looking upwards too. If you are in a town or city, you'll be surprised by how many beautiful architectural features are just above natural eye level. You might also see tufts of grass or even trees growing out of roofs and guttering. If you are in a park or in the countryside, you'll see all manner of things from birds' nests to bees' nests hidden in trees and bushes.
Give yourself over to the experience as if it were the only thing that existed in the world. Every moment of every season has a host of sensory delights - regardless of where you live.
When you lose interest and would like to discover something new, let it go and wait until you discover something else that is attractive and delightful to you. Be like a bumblebee going from flower to flower. When you are full with one, go to another.
Take your time, move slowly, and see what comes.
