I've found that when I'm deciding to try out something creative or artistic, I start to look for techniques in other people's works when I might otherwise just be enjoying them on a surface level. Anyone can look at a work and say if it's pretty or not, if it seems well-designed, how it makes you feel, but when you start to ask how an artist does that, you quickly discover techniques that you may be able to apply to your own art, your own writing. You can even look at a list of techniques [1] and then start to identify when creators are using them, and how to use them effectively. The more you experience and the more you think about it, the more understanding and the more tools you have at your fingertips. And by forcing yourself to get into D&D, you're throwing yourself into a game that will help you develop that variety of skills, and probably into a scene where plenty of people know enough of those skills that you can rapidly learn from them, see what they do brilliantly and see what they could do better.
