What is the suit of clubs all about?
If hearts stand for childhood, clubs stand for adolescence, which is all about rebellion, learning, and getting a sense of self.
Perpetual LEARNING! Being a student. Having lots of books. Loving learning so much that you might have a degree, or two, or three!
Feeling like the perfect information is out there somewhere and if you just learn it, your life will be complete.
Probably most of the money that gets spent in bookstores is spent by clubs. And a lot of your professors were probably clubs too. Clubs take learning very seriously. They love the written word too.
