Richard Nelson Bolles

One of the saddest lines in the world is, 'Oh come now - be realistic.' The best parts of this world were not fashioned by those who were realistic. They were fashioned by those who dared to look hard at their wishes and gave them horses to ride.

Always define WHAT you want to do with your life and WHAT you have to offer to the world, in terms of your favorite talents/gifts/skills-not in terms of a job-title.
