I still enjoy the other successes, like regular season wins, winning the division, getting high seeds in the playoffs, players getting awards and recognition, breaking records, winning playoff games, etc.
Of course, it doesn't equal a superbowl win. That trumps everything. But I derive satisfaction and entertainment from the lesser winning as well. It doesn't mean, for me at least, that I am content or that I am fine not winning a superbowl. That is always the goal. But I take a more nuanced approach and allow myself to enjoy the successes as they come.
