For me it was 100 pounds of popcorn.
Not actual popcorn, mind you, but a book I read in the second grade called "100 Pounds of Popcorn," written by Hazel Krantz. Reading it again now, it's a pretty standard Beverly Cleary style children's story featuring a whole host of wholesome 50's characters (think "Leave it To Beaver"). But what sets this particular book apart from others I read as a child is that its plot revolves entirely around what it takes to be a successful entrepreneur.
