Keep dreaming as you did in your youth, for the act of dreaming evokes creative energy and is healthy for you, as well as the world.
Dream not so much of material things, but rather who you can become and what you will experience as a result. Do not worry about the “hows” . . . simply dream.
Think not of the limitations spoken by the world, of what you can or cannot be. Todays perceived limitations are tomorrow’s history of what was.
