People are influenced most by those they trust, admire and believe care for them.
I've seen that phenomenally successful people believe they can learn something from everybody. I call them 'mavericks with mentors.' Richard Branson, for instance, is a total maverick but he surrounds himself with incredibly successful, smart people and he listens to them.
A lot of people have the ambition, but they never ask themselves, Do I really believe I can do this?
Ambition has to be joined with expectancy. A sense that you have a dream for yourself that you believe can happen.
