Such as, to pick a startup at random, online ticket sales? Is that -- by itself, without any consideration of reward or profit -- worth the sacrifice? The answer for this, and for 99% of other startups, is HELL NO.
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.
