    When I was 7 years old,I felt really happy for the first time in my life.I remember that my teacher allowed each student to play various educational games in tum on a computer designed for teaching.One day,I found the source code(编码)for one of these games.Without knowing or being taught any programming language,I was able to figure out some of the BASIG code.I just gave myself an interminate number of lives in the game,so I could continue playing it forever.This was also my first introduction to algebra(代数),and I didn't even know it at the time.This was a decisive moment in my life.I was quite excited because of what I was learning and what I was able to do.As a result,I was enthusiastic(充满热情的)for the rest of my life about self-learning and computers,and I was quite happy doing them too.

    I've noticed that people who are truly content with life are enthusiastic about what they do.This enthusiasm, along with good health,is the key to being happy.It also leads to self-confidence and content in life too.It may also lead to success,wealth,and achievements.

    Success,wealth,or achievements can also bring some people happiness,yet I know plenty of rich people who are unhappy.I know many people with successful businesses that are not happy with what they are doing.I know people who continuously buy themselves new toys,such as cars,computers,and televisions,yet never seem content for too long.Please remember,happiness is the journey of life,not the destination.

    A woman's home is her castle. She cleans, cooks, decorates, repairs, works, plays and relaxes within the walls of her home. Sometimes women choose to stay at home to raise their children instead of working outside of the home. So you think she must be bored. I was one of those women.

    After finally getting pregnant, and giving birth, I found my home to be the best place. During the nine months I carried my daughter, my body had been broken and back. Being able to relax was just what my weak body needed. Besides, nursing was a rest because I home certainly cured my broken body.

     other families grow one child after the next was a horrible dream, when I didn't think I would ever be able to have my own child. But after having Alyssa, my own cute little baby girl, I was e to let my heart recover from the wounds. I watched and I valued every small change of her body and personality. Nothing was more exciting than time spent with my child. I loved to stay at home.

    Mentally I remained challenged with new opportunities every day. I learned to be perfect and organized. Everything worked like a clock. By 9:00 in the morning, the house was clean--beds made, bathrooms cleaned, house cleaned, and windows cleaned. I enjoyed finishing them quickly so that I could devote most of the day to my daughter. Between nursing, short breaks and staring at her, I thought of ways to improve my home and myself. Even with all the housework, every day was filled with so much fun!
