Every time someone is on the cover saying I'll win, they lose. I remember Igor de galdeano on the cover of cycle sport a couple of years ago, saying "Of course I can win the vuelta." And he didn't even finish, got injured and bailed. Of course, he didn't say i WILL win. Neither did lance, he said he doesn't intend to lose. The best way to lose is to day I will win this. I remember Erik Dekker talking about when he won Amstel Gold and beat lance. He said he was thinking "I can lose this", because whenever you think ,I can win this, that's when you lose.
Makes sense, if you think that way you start screwing and getting careless.
You can catch more flies with honey than with vinegar. That's great...if you want to attract vermin.
