Because it's hard and uncertain. You can spend hours and days on a problem and not be sure of finding an answer. You need to be driven by a passion to overcome the obstacles. When my son was studying Electrical Engineering, he told me a story about how, at the beginning of every semester, a student would ask the professor if there was any programming involved in the course. The class would heave a huge sigh of relief if the answer was no. It's not that students were stupid. Rather, they had a big course load, were pressed for time, and could not afford the bottomless time hole of programming assignments. They knew that the time they invested in lab work or math assignments, would surely result in success. Not so with programming bugs.
