Article: If you have ever been discouraged because of failure , please read on. Usually, achieving what you set out to do is not the important thing. Let me explain. Two brothers decided to dig a deep hole behind their house. As they were working, a couple of older boys stopped by to watch. "What are you doing?" asked one of the visitors. "We plan to dig a hole all the way through the earth!" one of the brothers answered excitedly. The older boys began to laugh, telling the younger ones that digging a hole all the way through the earth was impossible. After a long silence, one of the diggers picked up a jar full of spiders , worms and a lot of insects. He removed the lid and showed the wonderful contents to the visitors who were laughing at them. Then he said quietly and confidently, "Even if we don't dig all the way through the earth, look what we found along the way!" Their goal was far too difficult, but it made them dig. And that is what a goal is for--to make us move in the direction we have chosen. In other words, it sets us to digging! But not every goal will be fully achieved. Not every job will end successfully. Not every hope will come to pass. Not every love will last. But when you fall short of your aim, perhaps you can say, "Yes, but look at what I found along the way! Look at the wonderful things which have come into my life because I tried to do something!" And I believe it is the joy in the journey, in the end, that truly matters.

Article: If you're not a fan of KFC's famous Double Down hot dog, don't worry! KFC in the UK is developing a new treat: an edible coffee cup. The product is still in the trial stage and not yet available for purchase, but according to a KFC news report, the treat is made from a unique biscuit, wrapped in sugar paper, and lined with a layer of heat-resistant white chocolate, which helps keep the coffee hot. As you drink the coffee in the cup, the white chocolate lining will begin to melt slowly, and the biscuit begins to soften. But it doesn't end there --- the cups are not only edible, they also have a pleasant smell. KFC partnered with The Robin Collective, an experimental food company, to make the cups with coconut sun cream, freshly cut grass and wild flowers scents. According to the news report, that's because the scents arouse the positive memories we associate with warm weather, sunshine and summer holidays. Sounds ... delicious? A manager at KFC said, "We have been experimenting with the edible packaging in limited quantities to see if it could be a popular product in the market. We believe if our customers occasionally like to have their cake and eat it, why wouldn't they want to have their cup and eat it instead! " The edible cups will only be available in the UK when it comes out. According to a spokesperson for KFC, there are at present no plans to bring it to the U.S. yet.

question:
Article: "A good parent" can be a confusing phrase. It is almost impossible for one person to be "a good parent" at all stages of a child's life. Some parents are at their best before their children begin to speak. Others are most successful before their children enter elementary school. Still others make their finest contribution to older children or teenagers. Every parent can understand one stage of a child's development better than another. It is hard for a person to possess superior capacities throughout the entire period of a child's growth. A mother might be "a good parent" from her baby's birth until it is three; that is the period when it needs her protection and loving care. Then the start of her child's independence might upset and alarm her, and she might then become less helpful for a few years. A father might be awkward and uncomfortable with a younger child, but could turn into an excellent parent when the child is old enough to be taught the skills of cycling, fishing and so on, or to be taken on trips. Some parents feel easier with boys, and others with girls -- and then only at certain ages or stages. It is important for parents to understand and accept their own limitations in these matters, just as they must accept the child's faults of personality and limitations of talent. Otherwise, fathers and mothers will feel guilty and blame themselves for weaknesses that may not be their faults. Much of the guilt experienced by modern parents comes from the mistaken feeling that they ought to be all things at all times to the child, which is clearly mistaken. In past ages, grandparents and uncles and aunts lived with the family, and provided different kinds of support; in our present "nuclear" family, too many roles are demanded of the two parents, which they cannot possibly fulfill.
