Hahah, let me tell you how. When I'm explaining computer science to someone who wants a capsule explanation, I don't tell the "computer science studies the problem X Y and Z, along with their generalizations", I say: "Computer Science studies the limits of human thought, trying to understand exactly how hard a particular idea is to think, and what sort of problems it is reasonable (for various notions corresponding to best, average, worst case complexity)to ask a person to solve".
