Writing programs gives you the power to control your PC.
Almost everyone knows how to use a computer, but few people take the next step and
learn how to control it. If you use other people’s software, you will always be limited by
what other people think you want to do. Write your own programs and the only limit will
be your own imagination. Programming will make you more creative, it will make you
think more precisely, and it will teach you to analyze and solve problems logically.
