Slumps are not forever, and neither is perfection. If you start off slow, you're one hit away from a hot streak.
There's a great book from the late 80s by George Will called Men At Work. In it, Hershiser is asked whether he goes to the mound in the first inning planning to pitch a complete game. ‘A perfect game,’ he replies. ‘If they get a hit, then I am throwing a one-hitter. If they get a walk, it’s my last walk. I deal with perfection to the point that it is logical to conceive it. History is history, the future is perfect.’
