Imagine your life is a big canvas. Picture it in your mind and think about the beginnning of your painting of life.You're fourteen yours old, and you are lucky if you have one seventh painted. Now imagine the rest of the canvas is totaly empty. Every day you live, and every month and every year, means another inch that is painted on that canvas. You're going to be painting this empty canvas with your life and when you get to the end of it, what is that painting going to look like?
