One of the things I have found has helped me with my prep time is my Game Master Binders. I have a few now and when people have seen them they have liked them. I use tables from various sources like the Pathfinder Game Mastery Guide, Sly Flourish’s books/blog, John Fourrs Tips, and anywhere else I can find something useful. I used to spend about an hour of prep time for every 3 hours of game time. Now I can prep a full session in about 15 minutes. The inspiration it gives me is amazing!
I have managed to come up with a lot of great ideas for campaigns too with some of these tables. Even though I have found something that works well for me though I am always open to suggestions on ways to improve or add to my binder. So please watch my video and if there is anything you would add or change anything please let me know.
