Somehow, my father and brother always looks annoyed when I raised up question about problem that might stand in way of their business plan. They see it like I'm being lazy or pessimistic. But I'm not. Okay, not optimistic or excited, but I usually prefer being neutral. Asking about problem is not because I'm pessimistic, but it's because I want to think of a solution for the problem. Those are not asked as unsolvable problem, but as a known-but-not-yet-solved problem.
