     New York city: It's a cold day in December. A little boy about 10-year-old was standing in front

of  a  shoe store on Broadway, barefooted  (光着脚),peering(凝视) through the window,  and  shivering (颤抖着) with cold. A lady walked to the boy and said, "My little boy, why are you looking so seriously

in that window? "

     "I was asking God to give me a pair of shoes. " The boy replied.

     The lady took him by the hand and went into the store, and asked the clerk to get  six pairs of socks

for the boy. She then asked if he could give her a basin(盆)of water and a towel. The clerk quickly

brought them to her. She took the little boy to the back part of the store and, taking off her gloves, knelt

down,washed his little feet, and dried them with the towel. By this time the clerk had returned with the

socks.Placing a pair upon the boy's feet, she then bought him a pair of shoes, and tying up the rest pairs

of socks gave them to the boy. She patted him on the head and said, "My little boy, do you feel more

comfortable now?"

     As she turned to go, the surprised boy caught her by the hand, and looking up iii her face! with tears

in his eyes, answered the question with these words, "Are you  Good's wife?"

     Are morning people born or made? In my case it was definitely made. In my early 20s, I rarely went to

bed before midnight, and I would almost always get up late the next moming.

     But after a while I couldn't ignore the high relationship between success and rising early. On those rare

occasions where I did get up early, I noticed that my productivity was almost always higher. So I set out

to become a habitual early riser. But whenever my alarm went off, my first thought was always to stop that

noise and go back to sleep. Eventually some sleep research showed me that I was using the wrong strategy.

     The most common wrong strategy is this: You assume that if you're going to get up earlier, you'd better

go to bed earlier. It sounds very reasonable, but will usually fail.

     There are two main schools (流派) of thought on sleep patterns. One is that you should go to bed and get

up at the same time every day. The second says you should go to bed when you're tired and get up when you

naturally wake up. However, I have found both of them are wrong if you care about productivity.

     If you sleep at set hours, you'll sometimes go to bed when you aren't sleepy enough. You're wasting time

lying in bed awake and not being asleep. If your sleep is based on what your body tells you, you'll probably

be sleeping more than you need. Also, your mornings may be less predictable if you're getting up at different

times.

     The solution for me has been to combine both methods. I go to bed when I'm sleepy and get up with an

alarm clock at a fixed time. So I always get up at the same time (in my case 5 a.m.), but I go to bed at

different times every night-sometimes at 9:30 p.m. and other times at midnight. Most of the time I go to bed

between 10-11 p.m.

     However, going to bed only when I'm sleepy, and getting up at a fixed time every morning is my way. If

you want to become an early riser, you can try your own.
