I think I finally found the secret: write for yourself.
I used to do this years ago, as a 14 or 15-year-old kid in high school. I did it because I enjoyed it. Then I became too enticed with the possibilities — money, fame, fortune, published books across all platforms, more money, movie adaptations, beautiful women on my arm at a book signing, etc. You can’t think that way because writing is not about those things.
Just … write. And enjoy the living hell out of it.
