In the first place, you shouldn't believe in promises. The world is full of them: the promises of riches, of eternal salvation, of infinite love. Some people think they can promise anything, others accept whatever seems to guarantee better days ahead, as, I suspect is your case. Those who make promises they don't keep end up powerless and frustrated, and exactly the fate awaits those who believe promises.
Paulo CoelhoKnowledge was always the power that kept the Universe in its place and the stars turning in their orbits.
