“Fortune leaves always some door open to come at a remedy.”

“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.”

“Happiness is something that comes into our lives through doors we don't even remember leaving open.”

“When one door closes, fortune will usually open another.”

“Leave the door open for the unknown, the door into the dark. That’s where the most important things come from, where you yourself came from, and where you will go.”

“In all human affairs, and especially in those that relate to war, …leave always some room to fortune, and to accidents which cannot be foreseen.”

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

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

“Not knowing when the dawn will come
I open every door.”

“I have an open-door policy when it comes to blame.”
