The Human Factor in Software Engineering

Recently, I read this motto, and I love it. Because when you invest time in a project, then you have believed in this project. And if it does not end as you expected, the idea probably still is as good as ever, but the form was not ideal. For instance, I have developed courses which I did not sell so far. One course became an e-learning course instead, another one will become a book soon. I still believe in the idea and do not want the idea and preparation to be lost. And finally: If the book sells great, people might want to experience the course in real, too. Anyway, I hate to dump 50-100 hours of work!
