“Every person who wins in any undertaking must be willing to cut all sources of retreat. Only by doing so can one be sure of maintaining that state of mind known as a burning desire to win, which is one of the essentials to success.”

~Napoleon Hill

“What this power is, I cannot say. All I know is that it exists…and it becomes available only when you are in that state of mind in which you know exactly what you want…and are fully determined not to quit until you get it.”

~Alexander Graham Bell
