Steve Jobs, the former head and co-founder of Apple Computer, was a college drop-out. At some point, he took classes in calligraphy. Calligraphy is probably something that few people actually use, so people thought that he was just wasting his time. They probably thought, “What are you going to do with calligraphy?”
But the calligraphy class later gave Steve Jobs the idea to use type fonts in Apple computers. At the time, PCs only used one style of computer type font. The type fonts helped to create the ground-breaking graphic style used today by Apple and all computers.
So sometimes you may be working toward your goal, and others may think you’re wasting your time, but the seemingly useless thing you’re doing today may turn into your dream job of tomorrow.
