Quote the first, from M.F.K. Fisher (in How To Cook a Wolf):

“It is all a question of weeding out what you yourself like best to do, so that you can live most agreeably in a world full of an increasing number of disagreeable surprises.”

Quote the second, from astrologer Chani Nicholas (sorry, Carl Sagan):

“Master the fine art of Giving The Right Fucks. We can’t care about everything, even if we wanted to be able to. We have to make choices. We have to be discerning. We have to direct our energy towards some things and away from others if we are to get anything done.”
