You know, it's really all about the attitude that you bring to life.
No matter what our circumstances are, all of us can look up from our daily lives and find reasons to be bitter, ungrateful, or feel like the world owes us more than what we have (i.e., in the NFL this would be like a Jason Peters). Or, we can choose to count our blessings and be thankful. Obviously, Nelson is one of the latter and not the former. And the Bills are better off for it - these are the guys you want on your team!
