A man wields a tremendous power for good or for evil who is welcomed into a million homes and read with confidence.

That's fine, and is all right so far as it goes, and in your case it goes very far.

Still, there remains more for you to do.
The public has built up for you a personality: now give that personality to whatever interests you in contact with your immediate fellow-men: something in your neighborhood, your city, or your State.
With one hand work and write to your national audience: let no fads sway you.

Hew close to the line.

But, with the other hand, swing into the life immediately around you.
