     What's the most important thing for you to have in your life? Somebody mentions hard-work, others

suggest knowledge, love and luck.

     If you arrange the 26 English letters alphabetically (按字母表的顺序) and use numbers to represent

each of them, for example, 1 for a, 2 for b, 3 for c…, you can change an English word into a number.

So hard-work becomes 8+1+18+4+23+15+18+11=98, meaning 98 is its mark; knowledge: 11+14+15+23+

12+5+4+7+5=96, while love: 12+15+22+5=54, and luck: 12+21+3+11=47, a small mark. None of these

words can give one a full mark. What about money or prayer (祈祷)? They can't, either.

     Then what else? Don't be worried. You can always find an answer to a problem in your life, when you

change your way of looking at things or doing things, or your attitude (态度). Yes, attitude is the word. See

for yourself: attitude: 1+20+20+9+20+21+4+5=100, a full mark.

     Different attitudes lead to different courses of life. Most times people hope for a better life. It is possible

that one will have a change for the better after one has changed one's attitude.

     When you change your manner and became friendly towards others, you'll meet more smiling faces

towards you. In the same way, if you take a positive (积极地) attitude towards failure (失败), you'll find it's

also rewarding though it has caused you losses.
