Some interesting window theme quotes.

For music/composing-

Composing is like driving down a foggy road toward a house. Slowly you see more details of the house-the color of the slates and bricks, the shape of the windows. The notes are the bricks and the mortar of the house.
Benjamin Britten

For reading/library -

“A house without books is like a room without windows.” 

Horace Mann

For outdoor ed/pe-

We've got to get people out of their cars, out of those drive-thru windows, get them walking, get them in parks and get them more active.
Mick Cornett

For a discussion about the American dream & equity-

Civil Rights opened the windows. When you open the windows, it does not mean that everybody will get through. We must create our own opportunities.

 Mary Frances Berry

Perspective-

Begin challenging your assumptions. Your assumptions are the windows on the world. Scrub them off every once in awhile or the light won't come in.
Alan Alda 

Education-

The whole purpose of education is to turn mirrors into windows.
Sydney J. Harris 

About photography-

These people live again in print as intensely as when their images were captured on old dry plates of sixty years ago... I am walking in their alleys, standing in their rooms and sheds and workshops, looking in and out of their windows. Any they in turn seem to be aware of me.
Ansel Adams 

other-

I need no dictionary of quotations to remind me that the eyes are the windows of the soul.
Max Beerbohm 

About discovery -

“I discovered windows one afternoon and after that, nothing was ever the same.”
  Anne Spollen, The Shape of Water
