It is a burden...(M)ake no mistake about that. Any great gift or power or talent is a burden and this more than any, and you will long to be free of it. But there is nothing to be done. If you were born with the gift, then you must serve it, and nothing in this world or out of it may stand in the way of that service, because that is why you were born and that is the Law.- Susan Cooper (Merriman The Dark is Rising)
