Add 10 moments where your protagonist struggles with inner conflict. Even if you think you have enough.
Ways to do this:
1. Divide your manuscript by 10 and add in a moment every x number of pages.
2. Identify 10 low tension scenes, setting descriptions, or expository passages and add inner conflict.
3. Find 10 scenes where the protagonist feels something (happy, scared) and add the conflicting emotion (sadness, bravery).
