Every Professional GM asks themselves the same questions: What if my players don’t like my games? How do I know if I’m doing a good job? What if I’m not good enough? Answering these questions can be very difficult as each of these are very subjective. Each GM has their own style, resources and preferences. What works for one, may not work for another. Listening to “Dos and Don’ts” is a good start but runs into the problem of subjectivity once the fluff is finished.
