“The first requisite for success is the ability to apply your physical and mental energies to one problem incessantly without growing weary.”

“[T]here’s a lot to be said for celibacy, for the concentration of your mental and physical energy.”

“Deep in the human nature there is an almost irresistible tendency to concentrate physical and mental energy on attempts at solving problems that seem to be unsolvable.”

“At the end of the day, it would be wise to turn all of your focus and energy on achieving mental over physical strength.”

“Nothing can be learned without mental exertion. If you are concerned in your further development, you will recognize the Christian word as to the curse of work as untrue. Work cannot be descended from sin, for it is a blessing. You will have experienced in yourself how elated one feels after successful physical or mental work.”

“Simply put, when you invite people’s best thinking and lead like a multiplier, your team will give you more—more discretionary effort, more mental and physical energy, and more of the fresh ideas critical for long-term success.”

“Success is the ability to go from failure to failure without losing your enthusiasm.”

“It is only because of problems that we grow mentally and spiritually.”

“Believe in yourself! Have faith in your abilities! Without a humble but reasonable confidence in your own powers you cannot be successful or happy.”

“Intuition is the energy of your being. When this pure energy starts flowing out from the unconscious level, it also heals you physically, mentally and emotionally. Apart from healing, it reduces stress and helps you to make decisions spontaneously.”
