But I had enjoyed working on the hard projects I'd encountered in my programing class back in high school. They were challenges I wanted to overcome. I changed my major and dove into college CS courses, which were full of hard problems -- but hard problems that I wanted to solve. I didn't mind being frustrated for an entire semester one year, working in assembly language and JCL, because I wanted to solve the puzzles.
