“LACK OF SELF-DISCIPLINE. Discipline comes through self-control. This means that you must control all negative qualities. Before you can control conditions, you must first control yourself. Self-mastery is the hardest job you will ever tackle. If you do not conquer self, you will be conquered by self. You may see at one and the same time both your best friend and your greatest enemy, by stepping in front of a mirror.” 

“The strongest oak tree of the forest is not the one that is protected from the storm and hidden from the sun. It's the one that stands in the open where it is compelled to struggle for its existence against the winds and rains and the scorching sun.”

“Cualquier hombre es educado si sabe dónde adquirir el conocimiento cuando lo necesita y cómo organizar ese conocimiento en planes definidos de acción.”

“Sería muy útil que todo aquel que lea este libro haga un inventario de sus bienes intangibles. Un inventario así podría revelar algunas posesiones invaluables.”

“The best recommendation is the one you give yourself by rendering superior service – with the right mental attitude.”

“Let us consider the power of FAITH, as it is now being demonstrated, by a man who is well known to all of civilization, Mahatma Gandhi, of India. In this man the world has one of the most astounding examples known to civilization, of the possibilities of FAITH. Gandhi wields more potential power than any man living at this time, and this, despite the fact that he has none of the orthodox tools of power, such as money, battle ships, soldiers, and materials of warfare. Gandhi has no money, he has no home, he does not own a suit of clothes, but HE DOES HAVE POWER. How does he come by that power? HE CREATED IT OUT OF HIS UNDERSTANDING OF THE PRINCIPLE OF FAITH, AND THROUGH HIS ABILITY TO TRANSPLANT THAT FAITH INTO THE MINDS OF TWO HUNDRED MILLION PEOPLE. Gandhi has accomplished, through the influence of FAITH, that which the strongest military power on earth could not, and never will accomplish through soldiers and military equipment. He has accomplished the astounding feat of INFLUENCING two hundred million minds to COALESCE AND MOVE IN UNISON, AS A SINGLE MIND. What other force on earth, except FAITH could do as much? There will come a day when employees as well as employers will discover the possibilities of FAITH. That day is dawning. The whole world has had ample opportunity, during the recent business depression, to witness what the LACK OF FAITH will do to business.” 

“Before we can master an enemy, we must know its name, its habits, and its place of abode.”

“el éxito no necesita disculpas, y el fracaso no acepta excusas”

“Success begins with a fellow’s will— It’s all in the state of mind.”

“It is the personalities back of a business which determine the measure of success the business will enjoy. Modify those personalities so they are more pleasing and more attractive to the patrons of the business and the business will thrive. In any of the great cities of the United States one may purchase merchandise of similar nature and price in scores of stores, yet you will find there is always one outstanding store which does more business than any of the others, and the reason for this is that back of that store is a man, or men, who has attended to the personalities of those who come in contact with the public. People buy personalities as much as merchandise, and it is a question if they are not influenced more by the personalities with which they come in contact than they are by the merchandise.

“Remember that it is not the lawyer who knows the most law, but the one who best prepares his case, who wins. If your "case" is properly prepared and presented, your victory will have been more than half won at the outset.

“THE "depression" was a blessing in disguise. It reduced the whole world to a new starting point that gives every one a new opportunity.”

“Fears are nothing more than a state of mind”

“Every person who wins in any undertaking must be willing to burn his ships and cut all sources of retreat. Only by so doing can one be sure of maintaning that state of mind known as a BURNING DESIRE TO WIN, essential to success.”

“Blessed is the man who has come to know that our muted thoughts are our sweetest thoughts. “Blessed is the man who, from the blackest depths, can see the luminous figure of LOVE, and seeing, sing; and singing, say: "Sweeter far than uttered lays are the thoughts I have of you.”
