What is success? I am not going to try to explain success. I think a precise meaning is impossible! Is it winning a Gold Medal at the Olympic Games or winning Wimbledon, or being awarded a Nobel Prize? What else? I believe personal success could be anything at all- it does not have to involve public recognition. Who is more successful? A millionaire who is unhappy, or an unnoticed person, who has led a simple, quiet, sincere and happy life? The simplest definition of success, I think, is “to set out to do something and to succeed in doing it.

    The first step on the road to success starts with belief. Believe you can succeed and you will. Achieving success in whatever endeavor(努力)you choose may be the goal of life; because it gives you freedom from worry. Could that be?

    Success means different things to every one of us. Some people believe it is measured in financial term; others believe it is helping others rather than helping themselves. However, most people are motivated to a great extend by public recognition. How many people are really happy? How many people are really doing what they want to with their lives? Incidentally, to imagine makes us different from animals.

    Most important of all, I believe success is a matter of personal growth. If every day you are developing or growing just a millimeter, I believe one is successful. Just being a slightly better person each day for me is success. I've got a very long way to go them!

    Finally, always remember success is a process and is not simply a matter of arriving at a destination. It's the journey that really matters. Success is what you become in the often very difficult and dangerous journey down the river of life.

    There's no doubt that water is vital to any life. About 60 percent of the average adult human body is made of water. This includes most of your brain, heart, lungs, muscles and skin, and even about 30 percent of your bones. Yet there's little scientific agreement about the exact amount of the stuff an individual should consume each day. So how much water do you actually need to drink to be healthy?

    You may have heard that you should drink eight 8-ounce glasses of water a day. Yet, the downside of this rule, researchers say, is that drinking water by the glass is not the only way that humans take in it. The “8 X 8” rule essentially overlooks two big sources of daily water consumption. One such source is food. Everything you eat contains some water. Watermelons, for example, are more than 90 percent water by weight. Different diets naturally contain different amounts of waters, and the counts. The other key water sources are other beverages. Non-alcoholic drinks such as coffee, and tea, contain mostly water and all contribute to your hydration（水量）.

    So, between all the food, water and other fluids you consume in a day, how much water should you aim to take in?

    The National Academics of Sciences suggests that woman consume a total of approximately 2.7 liters (91 ounces) of warm from all beverages and foods each day and men 3.7 liters (125 ounces). But these are just general guidelines.

    The truth is, there is no magic standard for hydration—everyone's need vary depending on their age, weight, level of physical activity, general health and even the climate they live in. The more water you lose, the more water you'll need to replace with food and drink. If you are looking for concrete advice, though, the best place to look is within. Drink up when you're thirsty.

    On plenty of drives with my mom through my childhood, she would suddenly pull over the car to examine a flower by the side of the road or rescue a beetle from tragedy while I, in my late teens and early twenties, sat impatiently in the car.

    Though Mother's Day follows Earth Day, for me, they have always been related to each other. My mom has been “green” since she became concerned about the environment. Part of this habit was born of thrift (节俭). Like her mother and her grandmother before her, mom saves glass jars, empty cheese containers and reuses her plastic bags.

    Mom creates a kind of harmonious relationship with wildlife in her yard. She knows to pick the apples on her trees a little early to avoid the bears and that if she leaves the bird feeders out at night, it is likely that they will be knocked down by a family of raccoons (浣熊). Spiders that make their way into the house and are caught in juice glasses will be set loose in the garden.

    I try to teach my children that looking out for the environment starts with being aware of the environment. On busy streets, we look for dandelions(蒲公英) to fly in the wind; we say hello to neighborhood cats and pick up plastic cups and paper bags. This teaching comes easily, I realize, because I was taught so well by example. Mom didn't need to lecture; she didn't need to beat a drum to change the world. She simply slowed down enough to enjoy living in it and with that joy came mercy and an instinct(直觉) for protection.

    I am slowing down and it isn't because of the weight of my nearly forty years on the planet, it is out of my concern for the planet itself. I've begun to save glass jars and reuse packing envelopes. I pause in my daily tasks to watch the squirrels race each other in the trees above my house.

    Last summer, in the company of my son and daughter, I planted tomatoes in my yard. With the heat of August around me, I ate the first while sitting on my low wall with dirt on my hands. Warm from the sun, it burst on my tongue with sweetness. I immediately wanted to share with my mom.

    There are so many expressions in American English that sound pleasant but are not.

    “Face the music” is a good example. When someone says they have to face the music, it does not mean they are going to a musical performance or concert. To face the music means to accept the unpleasant results of an action.

    Imagine a friend asks you to take care of her beautiful red sports car. She gives you the keys and says, “Thanks so much for watching my car while I'm away. But please do not drive it. It is an extremely fast car.” But you do not listen. You want to show off and pretend the car is yours. So, you drive it around town. As bad luck would have it, you lose control of the car and drive it into a stop sign. The damage is serious. When your friend returns, you must tell her what you have done and “face the music”. That could mean losing her friendship or paying for repairs to her sports car or both. Whatever the music is, you must face it.

    There are other American expressions that mean the same as “face the music”.

    To “take your medicine” means to accept the results from something bad you have done. And if someone says, “You made your bed. Now lie in it.” He means you created a bad situation and now you will experience the results, or as we say in American spoken English, you must deal with it!

    “Pay the piper” also means the same as “face the music”. But, that expression has its own very interesting beginning. We will talk about that on another Words and Their Stories.

    It's said that you don't know a man until you walk a mile in his shoes. And you also don't know what it's like for older people to travel until you accompany one on a trip.

    After flying with my elderly father from Washington, D.C. to L.A. in July, I began to realize that a companion has important tasks that can make a journey easier for older people. I booked nonstop tickets on JetBlue to avoid tiring, confusing connections, and we flew directly into small, manageable Long Beach Airport. Even though my father could walk, I arranged with the airline for wheelchair assistance, which meant we got on board first.

    When I took him back to the airport for his return flight to Washington, I got permission from JetBlue to wait with him at the gate instead of saying goodbye at the security checkpoint. I wished he'd had a first-class seat and access to a comfortable airline club. Better yet, I wish I had flown with him both ways. As I watched the attendant wheel him to the lift that took him from the tarmac (飞机跑道) to the plane, I felt like an anxious mom sending her child to school for the first time.

    I didn't need to worry about my father wandering away; at 82, his mind was sharper than mine. But his hearing was poor, so I worried about what would happen if he missed an important announcement. Fortunately, everything went just fine. Careful planning made the trip successful.

    Next time I travel with a senior, I'll know better. I hope there will be a next time.

    When the weather is good, most children would like to play outside. So we asked some kids and their parents whether the following toys kept them happy.

    All Surface Swingball, $35.99

    Played by Martin, nine, and five-year-old Alex in Crewe, Cheshire.

    Mother Jennifer says, "The boys thought the toy was excellent and really wanted to play with it. It can be played with alone or with another child. It's for the right age range but I believe the toy can be played with by all ages and is suitable for the whole family."

    Rubberwood Quoits Set, $13.99

    Played by Jessica, four.

    Mother Lucy Hayburst, 37, in Chichester, West Sussex, says, "Jessica played with this toy for a few minutes but quickly stopped playing with it. Since we bought this toy for her, she only played several times. The quality is very good. It can be played with by one child or more. Besides, I believe it's more suitable for older kids."

    Wooden Animal Skittles, $14.99

    Played by Matthew, two.

    Father Richard Lee, 36, from Dartford, Kent, says, "Matthew was very interested in the toys and liked to play with them, but that only lasted for around five minutes. The skittles were fun at first but that feeling soon disappeared. Two or more children can play with the toy together. And I think they are most suitable for kids aged between three and seven. Our youngest son, Ethan, just kept trying to eat the lion's head."

    First Tailball Net Set, $22

    Played by James, five.

    Mother Sarah Schwar, 39, from Grays, Essex, says, "James loved the toy." He enjoyed balls so it was perfect for him. We used it in the summer as it was easy to take on trips. It is suitable for kids over five years old. I think the price is fair and your children deserve it."
