A piece of white paper.
Sketch an idea or a plan. Draw lines and color the blocks. Take notes. Write a love letter. Turn it over. Do it all over again.
Fold it once. Then some more. Make a boat. Or an airplane to take flight. Cut it. Crumple it into a ball. Throw it at someone before running away with mischief. Ha!
What do you see? A blank canvas? A construction material to realize our wildest imaginations?
Life is like a piece of paper. What we choose to do with it is entirely up to us.
