We all have the power of thought – so what are you lacking? If you have willpower, then you can change anything. It is usually said that you are your own master.
When a man in the process of dreaming becomes conscious that he is dreaming, he is no longer identified with the phenomena; he is not affected exultantly or dolefully. God consciously dreams His cosmic play and is unaffected by its dualities.
True wisdom is less presuming than folly. The wise man doubteth often, and changeth his mind; the fool is obstinate, and doubteth not; he knoweth all things but his own ignorance… To be satisfied with a little, is the greatest wisdom; and he that increaseth his riches, increaseth his cares; but a contented mind is a hidden treasure, and trouble findeth it not.
