On setting goals and dreaming big

Here are some quotes I've been pondering lately:
"At a certain level, what we do at Disney is very simple. We set our goals, aim for perfection, inevitably fall short, try to learn from our mistakes, and hope that our successes will continue to outnumber our failures." -- Michael Eisner – CEO, Disney

Here's another quote that sums up the idea of "thinking big" for me:
"Shoot for the moon, even if you miss, you'll land amongst the stars.." -- Les Brown - motivational speaker

and here's a final quote:.
"...Don't merely dream big, dream beautifully..."  -- Walt Disney
