There is no mistaking a real book when one meets it. It's like falling in love. - Christopher Morley

You know at once, if you are clairvoyant in these matters (libre-voyant, one might say), when you have met your book. You may dally and evade, you may go on about your affairs, but the paragraph of prose your eye fell upon, or the snatch of verses, or perhaps only the spirit and flavour of the volume, more divined than reasonably noted, will follow you.

There is no one so grateful as the man to whom you have given just the book his soul needed and he never knew it. - Roger Mifflin

Wars are won in the mind before they can be won on the field.
