Similarly, I dropped out of university after one semester and went on to work as a web developer for the last five years. I helped to build one company and now have a standing offer to become a CTO for significant $$$ and lovely working conditions. I choose to forgo that offer in order to go back to school but that is because I want to become a scientist not because the lack of a degree in any way impeded my professional development. I do not agree that the want of any practical skill or piece of knowledge is a good reason to go back to school. Formal education is about credentials, which are needed to open certain doors.
