Imagination will often carry us to worlds that never were. But without it we go nowhere.
The world of reality has its limits; the world of imagination is boundless.
Logic will get you from A to B. Imagination will take you everywhere.
If you can imagine it; you can achieve it. If you can dream it; you can become it.
You're only given a little spark of madness. You mustn't lose it.
You will never win if you never begin.
Ralph Waldo Emerson
