The man who promises everything is sure to fulfil nothing, and everyone who promises too much is in danger of using evil means in order to carry out his promises, and is already on the road to perdition.
Carl JungIn the second half of life the necessity is imposed of recognizing no longer the validity of our former ideals but of their contraries. Of perceiving the error in what was previously our conviction, of sensing the untruth in what was our truth, and of weighing the degree of opposition, and even of hostility, in what we took to be love.
Carl Jung
