Besides the few calories you'll burn, regular walking can actually increase your body's metabolic rate, making it function more efficiently. Have a garden, even if it's just a row of bright flowers in front of the house. Besides the mental and spiritual benefits, studies are showing that touching the soil can have actual positive physical effects on your body. And there is nothing in the world as satisfying as sitting down to a meal of homegrown produce. If you sense your life needs changes, take one small step at a time.
Human beings have a very hard time with change, but small increments can be effected painlessly.
For instance, a cluttered house is the bugaboo of many a home-based entrepreneur. Start with a bag on the dryer for clothing the family can live without, and look at items carefully as they come out of the dryer. Go through drawers and closets before every gift-giving occasion, and add things you no longer use or need to the charity bag before new things come in. Before each child's birthday, hand him or her a bag, with the intention of filling it with the equivalent of the new things they expect to receive. Another biggie is quitting smoking.
