I subscribed to MasterClass a while ago. I think I watched 3 courses. Really enjoyed David Sedaris and David Mamet. Both Davids taught about writing. The only other one I watched was Bobbie Brown teaching about makeup. That was sort of okay. I think the overall experience is one of encouragement: You can do it too.
But are you really encouraged? Do you go on to do the things that are supposedly being taught, or are you only feeling something called encouragement, admiring somebody whose work you like, and nothing more?
