“To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.”
― William Shakespeare, Macbeth

“At present I absolutely want to paint a starry sky. It often seems to me that night is still more richly coloured than the day; having hues of the most intense violets, blues and greens. If only you pay attention to it you will see that certain stars are lemon-yellow, others pink or a green, blue and forget-me-not brilliance. And without my expatiating on this theme it is obvious that putting little white dots on the blue-black is not enough to paint a starry sky.”
― Vincent van Gogh

“There are no rules here -- we're trying to accomplish something.”
― Thomas A. Edison

“Love all, trust a few,
Do wrong to none: be able for thine enemy
Rather in power than use; and keep thy friend
Under thy own life's key: be check'd for silence,
But never tax'd for speech.”
― William Shakespeare, All's Well That Ends Well
