Here is a chapter i really liked :
Humanity cannot forget it's dreamers; it cannot let their ideals fade and die; it lives in them; it knows them as the realities which it shall one day see and know.
Composer, sculptor, painter, poet, prophet, sage, these are the makers of the afterworld, the architects of heaven. The world is beautiful because they have lived; without them, laboring humanity would perish.
He who cherishes a beautiful vision, a lofty ideal in his heart, will one day realize it.
Columbus cherished a vision of another world, and he discovered it; Copernicus fostered the vision of a multiplicity of worlds, and he revealed it; Buddha beheld the vision of a spiritual world of stainless beauty and perfect peace, and he entered into it.
Cherish your visions; cherish your ideals; cherish the music that stirs in your heart, the beauty that forms in your mind, the loveliness that drapes your purest thoughts for out of them will grow all delightful conditions, all heavenly environment; of these, if you but remain true to them, your world will at last be build.
