To be human is to have problems; it is to find problems, and it is also to create problems.
You do that; I do that. And yet imagine life without problems—that’s a surefire formula for boredom. Isn’t it? The fact is that we humans don’t thrive well unless we have problems.
That’s why we invent them: mathematical problems, puzzles, competitive games of skill. We need problems. And why perchance would we need problems? So we can be creative!
