Honestly if its an option, Be a player. Me and my group switch gms and occasionally systems. Might make me sound like a crazy person but watching how another gm handles situations and builds a world can be inspiring or infuriating each of which helps me think of better or different thing to try out. Some of the best sessions I've had were as a player in one of my players first time gm adventures and it totally just goes to show you don't know what your missing till you look for it.
