Impossible is just a big word thrown around by small men who find it easier to live in the world they’ve been given than to explore the power they have to change it. Impossible is not a fact. It’s an opinion. Impossible is not a declaration. It’s a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.
Imagination is more important than knowledge.
Life is like riding a bicycle. To keep your balance you must keep moving.
If you can't explain it simply, you don't understand it well enough.
--- Albert Einstein
