A closed windows let you see what is beyond your reach. Closed doors do not.

Closed windows still let you envision where you can go, while shut doors block your view and your path.

When windows open, they let fresh air in. When doors open, they let you out.

Windows of opportunity can provide you with the chance to see what’s possible, but you can’t get there until the door is open and you are ready to step through it.

Are you a viewer or a doer?

Most doors do not open themselves.
