As a child, you hear the word no about 15 million times a day, but I don’t know any child that has ever let that deter him or her in going after what they want. Children are relentless, creative, and determined and (even sometimes precocious) to get whatever it is they want.
So in your daily pursuit of trying to get what you want, be a little more child-like, creative, determined and relentless. Out of 15 million no’s, it only takes one yes. (No whining please)
