If you want to be a bad product manager, ignore the potential for future competition, especially from bigger and non-traditional competitors.
You need to focus on who your competition is now, and what you need to do to get ahead of them. Worrying about who might get in to your market is worthless — and if a big competitor comes in and wants your turf, there’s not a whole lot you can do anyway. Focus on the present and do what it takes to win, and wait to see what happens next.
