When I finally started writing and finding my own voice I had a really big success with the If You're Going to Be Evil series. It was shared on twitter, Facebook, and reddit (where it remained in the top ten D&D items for nearly a week). I thought, "Oh! This is what everybody wants to read!" So I chased that series and fucked it all up.
The truth is that you can't chase your audience by emulating your own past triumphs or the successes of other authors. Instead what you have to do is be yourself and break your own ground.You have to write about whatever is interesting to you on that day. Whether it's a short story about a sentient dungeon or you talking about sharing. No matter what you do though, you have to be yourself because there is only one +Zak Smith, only one James Maliszewski, and only one you.
