I’m not an educator, if anything quite the opposite, but if I were learning how to play roleplaying games I would want a step by step quided lesson like the guy with the perm who does the paintings. The method is not important, you aren’t making a masterpiece you are just trying to shake off the idea that you cannot do this. Yes you can, see me put the paint on my brush and put in happy trees. Once you’ve done a few of those you develop taste and hunger and can integrate more challenging approaches. Or you can keep painting happy little trees. Either way you are choosing where to stop and where to go but are taken to the start point and given the tools you need.
