As a starting point for discovering new books at the store.
Create a list of books that customers can browse at your retail store to find a book they already read. For each such book list suggestions for a new book they might want to read in the following format: if you liked this book because of X you might enjoy these books…” List potential books for each identifiable quality of the book they already read.
It’s always good to have a shortcut and start with the best book.

I would like to have all the great investor in “my club”. I would listen to what they say about the markets and decide who to follow on what trade.
Invite some of the great investors out there to form a private club. Members would pay to get into the club and have access to continuous information from these investors. The investors would give regular analysis and precise recommendations with explanations of when to trade, at what prices, when to sell and why they think this will work. Investors get paid based on the performance of their recommendations and how many took their advice.
