“When one door closes another door opens; but we so often look so long and so regretfully upon the closed door, that we do not see the ones which open for us.”

~Alexander Graham Bell

I believe this quote means that if you look at something as how it is and don’t see soemthing else that can help you up, then start being positive. Don’t look at the door you longed to pass through, look around you for other possibilities that can take you even to the same place you wanted to go to, or even better.
