To attempt to change the circumstances of your life before you change its imaginal activity, is to labor in vain. This I know from experience. I had a friend who hated Roosevelt, yet wanted him to change. Every morning while shaving, my friend would tell Roosevelt off. He found great joy and satisfaction in this daily routine, yet could not understand why Roosevelt stayed the same. But I tell you, if you want someone to change, you must change your imaginal activity, for it is the one and only cause of your life. And you can believe anything in if you will not accept the facts your senses dictate; for nothing is impossible to imagine, and imagining - persisted in and believed - will create its own reality.550 ¶4
