I did, I wanted to do too much and killed a story.
On my Ashcroft Legacy, story I wanted to try something simple: write a story with at least one picture in each chapter. It killed it, I got good ideas and then spent hours browsing for the perfect picture, while I thought the story would go fast it never got up and is now in the freezer. I'll maybe try to salvage it one day.
No-one forced me to do this but once I realize that I won't be able to follow my objective, I lost all motivation for this story.
