阅读下面短文，并根据短文后的要求答题（请注意问题后面的字数要求）。
［1］Why not take a more measured approach to a happier, healthier you? From your office to your bedroom to your car, these small changes can have a big impact on your life.
［2］Wake up ten minutes earlier. When you start your morning in a hurry, you set a stressful tone for the day. (I’m speaking from experience here.) Even ten extra minutes in the morning can help you feel more calm, collected, and ready to face the day.
［3］Spend five minutes in silence or meditation. You’ll soon realize, whether it’s in the morning or evening, that five minutes of sitting quietly with your eyes closed feels a lot longer than five minutes. But just this short silence can foster a quietness that carries through the day. When things go off the rails, simply close your eyes and recall that earlier quietness.
［4］Walk. Is there one trip you’d normally make in the car (to work, the gym, the store) that you can make on foot? Walking saves money (good for you) and gas (good for the environment) and burns calories (around 2,000 steps equal one mile), which is good for your health.
［5］Tell someone you love them. Life is never long enough to say this as many times as it should be said. Whether your mother, a friend, a significant other, or your dog, make it a habit to tell someone at least once a day that you love him or her. While it may feel strange at first, you will never regret it.
［6］Stand (or sit) up straight. Good posture prevents back and neck pain and even build confidence. When driving, tilt your rearview mirror（后视镜）up a bit. You’ll have to sit up to see. At your desk, the top of your computer screen should be at eye level. Put a small cushion in the curve of your lower back, and your spine will become straight.
