What new can I add?

Hi Brooke, I am working on creating a productivity course. It’s been a topic of fascination for me for a while and I learned so much about it over the years from various books and online courses.

When I am working on creating my course, I get surrounded by this negative thought that everything that can be said is already said in other books and courses. What new I can add? Nobody will want mu course.

As a result of this thought, I feel uninspired and stop making any progress.

Can you help me think new thoughts about this situation?

Thank you.
