Recently, I felt like I reached a very low point in life. My relationships weren't good, I wasn't enjoying my classes, and I felt like I had nothing to1.My life seemed to be full of endless homework, tests and loneliness. Nothing anyone said seemed2o me. I wasn't sure what to do about myself. All I wanted was to be happy again, but I didn't know who or what would3that.

    During these days, I had trouble sleeping. I had to take sleeping pills but still woke up in the midnight. I had no4but to tell my dad. He5the book The Secret. I immediately bought the e-book online and read the whole thing that night. I'm6quite a stubborn person, but the effect on my mood after finishing the book was7. Suddenly, I felt like life was beautiful again. I had never felt such a deep and quick8in my life before.

    In fact, the book's message was very simple—think positively(积极地).The book had many success stories about how people were able to9money, soul mates(心灵伙伴)and old friends back into their lives. I started learning to thank everything in my life like them. Little by little, I realized that The Secret could only work10I believed these people's success stories.

    Now I'm sure I can bring myself happiness.
