Not much happens without a dream. And for something great to happen, there must be a great dream. Behind every great achievement is a dreamer of great dreams. Much more than a dreamer is required to bring it to reality; but the dream must be there first.
I've never been someone that's had a five-year plan, or a three-year plan. That just seems to lead to a lot of disappointment, and doesn't give you the chance to be flexible.
