Orang sukses itu makmur, karena dia telah mengembangkan sembilan puluh lima persen kemampuannya. Kegagalannya buruk, karena hanya lima persen dari bakat alaminya yang telah dimanfaatkan. Asli: The successful man is prosperous, because he has developed ninety-five percent of his ability. The failure is poor, because only five percent of his natural talents have been utilized.
