Which one of these four quotes is attributed to Reinhold Niebuhr?
→ I don't know why we are here, but I'm pretty sure that it is not in order to enjoy ourselves.
→ God, give us grace to accept with serenity the things that cannot be changed, courage to change the things which should be changed, and the wisdom to distinguish the one from the other.
→ I said to my soul, be still, and wait without hope, for hope would be hope for the wrong thing; wait without love, for love would be love of the wrong thing; there is yet faith, but the faith and the love and the hope are all in the waiting. Wait without thought, for you are not ready for thought: So the darkness shall be the light, and the stillness the dancing.
→ A good vacation is over when you begin to yearn for your work.
