One of the things that impressed me most about Lewis Hamilton, even going right back to his karting days, was his 'never-give-up' attitude. However impossible things might look (either within a race or over a season) he would not let up; he would keep going, keep pushing, always believing that until the race was over anything might still happen. Schumacher shared the same attribute and though I was never a fan, I always admired this aspect of his racing.
Manchester United play football the same way and there has been many a game, or even championship, that they have won in the last few moments by refusing to believe that their chance was gone.
That's all.
