Not all closed doors are locked. But until you try to open the door, you will never know.
And sometimes, the key to a locked door is hidden nearby. But you would never find it if you don’t take a moment to look for it.
And some doors are just not meant to be opened at the precise moment when you arrive. But that might not be the case when you return to the same door at another time.
I agree and that’s why I say, “A closed door is an Option for some and an Opportunity for others.” You can make that close door what you want it to be because a choice is there.
