I remember the first time that I was extremely happy. I was about 8 years old when for the first time, there was a computer in the classroom. I remember that my teacher allowed each student to take turns playing various educational games on the computer. One day, I found the source code (密码) for one of these games. Without knowing or being taught any programming language, I was able to figure out some portions of the BASIC code.
Anyone who knows a bit of programming can tell you that I just give myself an infinite (无穷大) number of lives in the game, so I can continue playing 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 (决定性的) moment in my life. For the first time that I can remember, I was quite happy because of what I was learning and what I was able to do. As a result, I became enthusiastic 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 in what they do. This enthusiasm, along with good health, is the key to being happy. It also leads to self-confidence and fulfillment in life, too. It may also lead to success, wealth, and achievements.
Yes, success, wealth, or achievements seem to bring some people happiness, too. Yet, I don’t think they can indeed make people happy. I know plenty of people who are successful and wealthy. However, I also know several of the people with successful businesses are not happy with what they are doing. I know people who continuously buy themselves new toys, cars, computers, and televisions, yet they never seem content for too long.
Please remember that happiness comes from enthusiasm, and happiness is the journey of life, not the destination.
