I see Americans of every party, every background, every faith who believe that we are stronger together: black, white, Latino, Asian, Native American; young, old; gay, straight; men, women, folks with disabilities, all pledging allegiance under the same proud flag to this big, bold country that we love. That's what I see. That's the America I know!

I know that I am intelligent, because I know that I know nothing.

I decided to sell my drawings. However, I didn't want people to buy my drawings because the professor of physics isn't supposed to be able to draw - isn't that wonderful - so I made up a false name.

Those who educate children well are more to be honored than they who produce them; for these only gave them life, those the art of living well.

Many are they who have a taste and love for drawing, but no talent; and this will be discernible in boys who are not diligent and never finish their drawings with shading.
