Unconventional ideas for a brain training program or a series of books

I would like to write a series of books on training various mental abilities. The offer in this area is enormous. What could you do to make yourself stand out?

Some ideas so far: brain training with humor, 1950's style memory training for old people, minimalist brain training, train your creativity with Dr. Frankenstein.

Your input would be very much appreciated. ☺️
