For kids: help them have some structure to their story, and show them many different possibilities. For all: help them get going with their imagination, and have fun.
Have different card packs for different aspects of storytelling. Structure, genres (romantic, detective, fantasy etc.), time periods, style (narrated, first person etc.), atmosphere etc. Can also be done online (website, app), and an online community where the finished stories can be published.
There is a lot of information available. How can you find the pearls of wisdom in the huge stack of hay?
Get famous, rich, successful people to give their practical advice on many different subjects. Ask them to tell what they did that made them a success, in each area they think they have an advice to give or a story to tell that others can find useful. Then publish a series of books, one on each subject matter, and each one containing the practical advice of many of these successful people.
