     When I was a child, I could not wait to see the world. I grew like the spring flowers in the garden.   

     When I was a teenager, I could not wait to leave home. I did not want to follow any rules, and I was

as angry as the burning sun in the summer sky.   

      But then, I learned to think carefully before doing anything. Both good and bad things in the past became

parts of my life, like autumn harvests for a farmer.   

      Now I am old. My body is weak, but my mind has become strong and clear because of those experiences

in my younger days. I am like a winter leaf, ready to take a good rest.   

      These are the four seasons of my life.
