Once upon a time there was a woman who had a lovely garden in her back yard. She had no real income, so this garden was her only supply of food. She spent hours every day planting and watering in her garden and all her neighbors were impressed at her ability to grow the most beautiful fruits and vegetables.
One day when she went out to her garden, she saw an unusual plant right in the middle. It was a purple flower that stood straight up, only about half a foot tall. The woman was puzzled because she had never grown a flower that resembled this one. She came to the conclusion it was a weed and began to pull it out, but she stopped. This flower was not ugly and it was a nice centerpiece for the garden, so the woman left the weed in.
As time went on, the weed grew and grew, and as weeds do, it began taking over the garden, one square foot at a time. By this time, the roots were growing deeper, but the frail woman could have pulled it out if she wanted to, but it was so pretty that she let it stay. Eventually the plant not only required space but extra water, fertilizer and time on the part of the woman. When the woman gave these necessities, her neighbors warned her against wasting time and resources on the wrong thing, but she went ahead and did it.
