Whenever I am about to prune a leaf, I stop and ask myself, "why am I removing this leaf?" There are really only a few reasons to cut off a leaf.
1. It doesn't get enough light to be productive
2. You need better airflow towards the center of the plant
3. It's blocking light to other, potentially more productive, sites
4. It's sick and dying
If you can't honestly say you're cutting it for one of these reasons, then leave it be. Never cut more than 1/3 of your fan leaves in one sitting. Remember too, that whenever you cut a leaf, your baby is gonna spend some energy healing so it slows down productivity elsewhere for a bit. Find your center :)
