      I am a man who has been egoistic (自我为中心的) and I have had a lack of respect for myself

and others around me. I participated in(参加) various transformation workshops, however, it made

no difference. I remained stuck in my life. As a result, I became separated from my family and reached

rock bottom in my life. Having reached there, I resisted transforming myself.

      After some time, I thought to myself, start believing in yourself and it will make a difference in your life. I first started loving myself and then all those around me. I started respecting myself and then others around me. My selfworth increased.

      Sangeeta is my workmate. She's transparent, honest and respectful. She's very poor and has a large

family to support. In addition, her husband doesn't hold a regular job. In short, she's struggling in life.

      On a cold winter morning, when she came to work, I found her shaking. I asked whether she had a

pullover (毛线套衫). She didn't reply. I_had_my_answer. The next day when she came to work

again, I gave her the money to buy a pullover for herself. The expression of thankfulness in her eyes was

something that will remain with me for a long time.

      A few weeks ago, she was ill and didn't come to work. Instead, she sent her friend to do her work.

The moment I realized Sangeeta was sick, I gave her friend the money to buy medicines for her treatment. It took Sangeeta some time to recover from her illness. The first thing I cared about was whether she needed any more help of any kind. And she said, "Sir, you've done enough for me. I'm grateful to you."

      That was the moment when I realized that I'm walking my path. Sometimes, I still fall down, but I get

up and start walking again even though I may have hurt myself in the process.
