From MNBlockhead, "You are creating content that you will use to run a game for a group of players. It is easy to get lost in flavor text and background detail. Your focus is best spent on content that will help you run great games."

This is the main thing that I learned.

I enjoy filling in RW, it's pleasant, restful and gives me a sense of achievement - but if it's not information I'm going to need in game, that's all it's doing. Background is lovely, but I learned that it's most important to concentrate on information I'm actually going to need for my players.
