Revamping my course 'storytelling for founders'. What's that one thing I should definitely include?

I'm the founder of Crunchit.ai, and I've helped over 40 founders raise. I periodically revamp my course, and this time, I plan on launching it on Maven. If there was one thing this course could help you learn, what would it be? I'll reply to all your comments on Sunday, September 3rd and also inform you when the course with your suggestions goes live.
