“This is the shade of meaning: the door of a physician should never be closed; the door of a priest should always be open.”

“When one door closes, another opens… into another room, another space, other happenings. There are many doors to open and close in our lives. Some doors we leave ajar, where we hope and plan to return. Some doors are slammed shut decisively—"No more of that!" Some are closed regretfully, softly—"It was good, but it is over." Departures entail arrivals somewhere else. Closing a door, leaving it behind, means opening onto new vistas and ventures, new possibilities, new incentives.”

Helen Nearing (1904–1995) American writer

“Knowledge of what is does not open the door directly to what should be.”

Albert Einstein (1879–1955) German-born physicist and founder of the theory of relativity

“A door opens to me. I go in and am faced with a hundred closed doors.”

Antonio Porchia (1885–1968) Italian Argentinian poet

“I don't just pray for God to open doors, I also pray for God to close doors.”

Joyce Meyer (1943) American author and speaker

“You have to come to your closed doors before you’ll ever get to your open doors.”

“When one door is closed, many more is open.”

Bob Marley (1945–1981) Jamaican singer, songwriter, musician

“Choosing not to read is like closing an open door to paradise”

Mark Twain (1835–1910) American author and humorist

“When one door of happiness closes, another opens; but often we look so long at the closed door that we do not see the one which has been opened for us.”

Helen Keller (1880–1968) American author and political activist
