Business is just problem solving. It's like playing a slow paced, higher stakes video game that you get real money for beating instead of virtual money. Now, it's more complicated than even a complicated game, and the rules or winning conditions aren't always clear. But once you get acclimated, there can be a sublime beauty and enjoyment to doing almost any sort of business.

Smart people who don't initially like the more persona-driven types of business often become the best businessmen. Engineers, etc - business is just critical thinking, and getting it done. I've found enjoyment in many types of business, and just "doing business" (solving problems) is a right good time.
