“There is no "wrong train.”
“Amateurs train until they get it right. Professionals train until they cannot get it wrong.”
“If you board the wrong train, it is no use running along the corridor in the other direction.”
“The only side effect of too much training is that you get into better shape. There is nothing wrong with that.”
“The train is roaring toward you and the villain is twirling his moustache and you're fussing that he's tied you to the tracks with the wrong kind of rope.”
“The use of self control is like the use of brakes on train. It is useful when you find yourself in wrong direction but merely harmful when the direction is right”
