“Let me give you a piece of advice. The handsome young fellow who's trying to rescue you from a hideous fate is never wrong. Not even if he says the sky is purple and made of hedgehogs.”

Variant: The world will try to change you into someone else. Don't let them. That's the best advice anyone can give you.

Context: After all, there's only one answer to be made to the young fellow who is asking constantly for advice as to how to hit. The answer is: "Pick out a good one and sock it!" I've talked to a lot of pretty good hitters in the past ten years and I've watched them work. Go over the list from top to bottom—Hornsby, Goslin, Heilmann, Gehrig, Traynor, Cobb, Judge, Bottomley, Roush—there's not a "guess" hitter in the lot. They all tell you the same thing "I never think about whether it's a curve or a fast one that's coming. I simply get set—and if the ball looks good, I sock it."
