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.
