I've come to embrace the notion that I haven't done enough in my life. I've come to confirm that one's title, even a title like president of the United States, says very little about how well one's life has been led. No matter how much you've done or how successful you've been, there's always more to do, always more to learn, and always more to achieve.
Focusing your life solely on making a buck shows a certain poverty of ambition. It asks too little of yourself. Because it's only when you hitch your wagon to something larger than yourself that you realize your true potential.
Nothing in the world is worth having or worth doing unless it means effort, pain, difficulty… I have never in my life envied a human being who led an easy life. I have envied a great many people who led difficult lives and led them well.
The leaders we revere and the businesses that last are generally not the result of a narrow pursuit of popularity or personal advancement, but of devotion to some bigger purpose. That's the hallmark of real success. The other trapping of success might be the by product of this larger mission, but it can't be the central thing.
It is within your power to see that all you have experienced, trials, errors, faults, deceptions, passions, your love and your hope, shall be merged wholly in your aim.
