My husband bought this book How Successful People Think by John C. Maxwell, and one day in a state of boredom, I opened it up directly to the chapter I desperately needed to hear.
(most of the content below is blatantly plagiarized but this is only a tiny fragment of the excellence in this book so I urge you to go buy it)
Possibility Thinking Gives you Energy
Who gets energized by the possibility of losing? Are you going to put two hundred percent into something you believe will fail?
Stay Away from the "Experts"
Experts do more to shoot down people's dreams than just about anybody else. John Andrew Holmes said, "Never tell a young man something cannot be done. God may have been waiting centuries for somebody ignorant of the impossible to do that thing."
Dream One Size Bigger
Have Stephenie Meyer dreams and J.K. Rowling fantasies? You're thinking too small. If you set your goals high, you have more room to grow and you will believe in greater possibilities.
Henry Curtis advises, "Make your plans as fantastic as you like, because twenty-five years from now, they will seem mediocre. Make your plans ten times as great as you first planned, and twenty-five years from now you will wonder why you did not make them fifty times as great."
