In business, it's often important to consider some deep questions about where you're going and what you're trying to achieve. But that can get tiring from time to time, so it's nice to think about some fun topics instead.

For example, I routinely like to consider which came first, the chicken or the egg? I come up with a different answer every time, but the important thing is the reasoning behind it. Playing this with children is fun because it teaches them to come up with logic and reasoning rather than just guess.

Another one is the age old "If a tree falls in the forest and no one is around to hear it fall, does it really make a sound?" I think this one is just as bad as Schroedinger's cat, and just as loopy. But again, it's fun to consider it, isn't it?
