I love Sly Flourish's blog for DM information. The Lazy DM is a fantastic book to build an adventure using a grounds up sandbox approach where the players play a big part of how the narrative develops. Better yet, it's done with minimal preparation and talks about how to invest in preparation to make the game better for the players. ***LINK***
It's a little easier to digest than the Dungeon World campaign building, and DW has great general information for running games: ***LINK***
I also can't recommend watching Critical Role enough, where a group of voice actors play 5e with an excellent DM in charge. They mention several tools in the show like Fight Club, and Matt Mercer (the DM) makes several DM tips videos as well. ***LINK***
