“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 built.”

As A Man Thinketh (1902), Visions and Ideals
Context: In all human affairs there are efforts, and there are results, and the strength of the effort is the measure of the result. Chance is not. Gifts, powers, material, intellectual, and spiritual possessions are the fruits of effort; they are thoughts completed, objects accomplished, visions realized.
The Vision that you glorify in your mind, the Ideal that you enthrone in your heart — this you will build your life by, this you will become.

As reported by Heraclides, son of Sarapion, and Diogenes Laërtius, in Lives and Opinions of Eminent Philosophers, "Pythagoras", Sect. 7, in the translation of C. D. Yonge (1853)

Context: I read the other day some verses written by an eminent painter which were original and not conventional. The soul always hears an admonition in such lines, let the subject be what it may. The sentiment they instil is of more value than any thought they may contain. To believe your own thought, to believe that what is true for you in your private heart is true for all men, — that is genius. Speak your latent conviction, and it shall be the universal sense; for the inmost in due time becomes the outmost, — and our first thought is rendered back to us by the trumpets of the Last Judgment.
