    On a cold winter day, I waited in line to see my hero, Jack Canfield, the author of The Success Principles. During his talk, Jack1 his wallet, pulled out a hundred-dollar bill, and said, “Who wants this?”2 shot up in the audience. People leaned forward to see whom Jack would3. But I jumped up, ran to the4, and caught the bill. As I turned and5 the audience, thoughts raced through my mind—was I about to be humiliated (羞辱) in front of 800 people? Would they6 security guards and take me away from the stage? 7 my desire for the money was louder than any8 voice. When I got the bill from his hand, he said, “That's it! We can't wait for the 9to come to us. We must take action to10 what we want!”

    After his talk, 1 managed to formally meet Jack and bravely asked for his11 email address. Over the next months, I sent him emails 12 my dreams to him. He kindly emailed back lots of encouragement. But I was13with other things. I stopped e-mailing Jack.

    A year later, my dreams were broken. I thought Jack would14 me to take action, like a huge arrow that would show me the way.

    I emailed him, and then again—but got no15. As I sat down at my computer to check my emails, I 16 woke up. What was I doing? I was waiting! Now I remembered the crowd17 the money, but they just sat on their chairs18.

    Usually we all have a “Jack” for whom we wait—whether it's a person, a place or a thing. We19 believe the gifts of life are just around the corner, and that everything will come in a(n) 20way. So we don't try. We give up. But as Jack said: “You'll always miss 100% of the opportunities you don't take!” So I stopped waiting and started my writing career. Now what are you waiting for?

    When I was in middle school, my father went to my school and drove me home every Friday afternoon. On the way home, we usually talked and laughed. How happy we were!

    One day, my 1 was driving me home as usual. But to my surprise, he didn't say a word 2 the way home. It seemed that he was not very well. "Are you sick Dad?" I asked him. "No, dear. Don't worry," he answered.

    Later at home, I found my father smoking in the balcony(阳台). And I knew he had stopped 3 many years before. Something must be wrong with him. So I went to my mother and told her about my worries. My mother 4 me that my father had been out of work for several days, and he hadn't got a new 5 yet. Hearing this, I felt sorry and 6. Whenever I had 7 , my father always encouraged me. The next day, I made a card for my father. I wrote some words on it to 8 him. My father was moved to tears. He hugged me and said," Thank you, dear. Everything will be fine soon."

    Our parents always take good care of us, 9 some of us never think about them. How selfish we are! As teenagers, we should not only care about ourselves, but also 10 our parents and other people

    Last December, just a week before Christmas, I went to a local KMart store to pick up my layaway(预付定金购物). Upon reaching the counter, I 1 the clerk my layaway receipts and told her I was there to pay off the balance and take the  2 home with me. She grabbed my receipts, and kept messing with the computer 3 something was wrong. I felt a little uneasy. I was4 her to tell me my layaway had been misplaced or something of the sort.

"I couldn't believe what I was hearing! This kind of story only happens in the 9. Why was my family 10 to receive such a blessing?

It definitely 14 my heart. However. I felt 15. I kept thinking that perhaps some family out there was not going to have a Christmas because they really couldn't 16to pick up their layaway.

    I decided to pay it 17, so I used the money I had for the balance on my account to purchase some 18 and on my way out, I gladly 19 them off inside a huge toy donation box. Since I had received such a nice, heart warming gesture from someone, I wanted to keep the 20 going. And it felt nice to receive and to be able to give right back.

    Here's one touching story about two heroic teachers. When a1filled with schoolchildren went madly out of control, their teachers stayed cool to deal with the emergency. It was the quick reaction of the teachers that saved scores of lives.

    It was 6 a.m. They were 2the May day field trip. As the kids waved goodbye to their parents and boarded the bus, their teachers Tina and Kelly settled into front seats. The teachers were whispering quietly3they felt the bus switched its direction suddenly across the highway and4into the guardrail(护拦). The driver was stuck in by his seat belt and his head was just kind of hanging there.

    The children seemed frightened and screamed in5.

Both the teachers comforted their students and kept telling them to6down.

    Meanwhile, the bus ran 7down the highway at 70 miles an hour.

    In a second, Tina made her decision.8over the driver, she put her hands on the wheel and tried9to pull it back to the right.

    However, the bus didn't react as10. Instead, it was beyond Tina's11and turned over into a deep grassy valley, sending Tina through the front window of the bus. She was severely12. The bus slipped through the grass on its roof for several yards13 it finally stopped and the 14began struggling their way out through the broken window.

    Luckily,15of the children were killed. Not only had Tina droved the bus toward a safer place,16her gentle right turn also slowed down the bus speed, when it17into the valley. Obviously, she reacted properly and did an impressive job.

    Tina was rushed to the hospital for a(an)18by air. After she recovered from the operation, she returned to school, receiving cheers and praise,19she seemed embarrassed by all the attention. "I'm not a hero, I just did the best I could." she said, adding, "All those kids will be20to me, for we escaped from the jaw of death together."

    I was late for the school bus and rushing to get ready. My dog, Tippy, got to the front door and lay down in front of it – his way of asking to be petted. I1his begging for affection (喜爱), hurdled(跨) over him and ran for the waiting bus.

    2, that afternoon, when I came home, Mom said to me3, "Honey, I have some4news that I need to tell you. This morning, while you were at school, Tippy was hit by a car and5 I'm so sorry."

    "No! It's not true!" I was6 I couldn't believe her. "Tippy, come here! Come on, boy!" I called and called for him. I waited. He didn't come. Feeling7, I wandered into the living room. I didn't cry that night. I still couldn't believe that he was8.

    When I got off the bus the next day, there was dead silence at home.9 my sobs (哭泣) bubbled up and erupted (喷发) like lava (熔岩) from a volcano. I couldn't stop10. I hadn't even petted him when I left.11could I have known that was my last chance? I cried until I felt empty inside.

    Time passed, and against my will, I started to12some things. I realized what little control any of us have over what happens 13 a dog. We can do everything right, but14things can still happen. But good things can happen too. That's15. The best way to 16 the hard times is to figure out what you need to do to get through them when they come, and to remember that hard times always17.

    I now deeply understand the "circle of life". Everyone is born, everyone18, and that's the way it is. If dogs never died, there would be no19for others like Belle – my new dog.

    Best of all, I realized that Tippy20all of my good memories of him. And they come to me every time I call!

    When my wife, Jane, and I were 16, we were in the same class. About a week before Thanksgiving Day, we found out that our teacher Edward was having some 1challenges. We wanted to do something to help, so as a class we 2to gather food, clothing and gifts to 3his family had a good Thanksgiving Day.

    When Jane told her family about our plan, her mother was 4. Together they searched their house for things they could 5. Her mother went to the kitchen, 6 a big turkey and saying, "Thanksgiving Day won't be 7without a turkey dinner." To this day, Jane remembers how moved she was by her mother's 8.

Before making our 9, we said a prayer of appreciation for the wonderful 10 to help others. I will never forget the surprised 11 of our teacher and his wife when they 12 the door; their four children gathered around them as we handed out the gifts. It was a cold night; we all felt warm inside, 13.

    Last month while I was in a meeting, my secretary informed me, "Your high school teacher Mr. Edward is wondering if you could 14 him a few minutes. He's sitting in your office right now!"

    I left my meeting and went to my office 15. My teacher and I hugged and began to 16 the last 42 years. He told me he 17 remembered that cold winter night when we brought the 18of Thanksgiving Day to his family. The food and gifts were certainly appreciated, 19what warmed his heart that night was to see a group of teenagers who understood the 20of Thanksgiving Day.
