>I'd say great product trumps luck. Because without a product all that luck can get you is a winning lottery ticket.Of course you would say that, because that's your experience. In your case, the entry fee to the lottery was creating a great product, doing marketing, and generally hustling - just like your competitors. Once you paid the entry fee though, the controlling factor was luck. You won, and your competitors lost. I am not trying to take anything away from your success, because you paid your entry fee through hard work, but as I said it shows a lack of perspective to just say "we are successful because we made a great product". Great products fail every day.
