“Deign on the passing world to turn thine eyes,
And pause a while from learning to be wise.
There mark what ills the scholar's life assail —
Toil, envy, want, the patron, and the jail.”

Context: Sometimes you're invited to a big ball and for months you think about how glamorous and exciting it's going to be. Then you fly to Europe and you go to the ball and when you think back on it a couple of months later what you remember is maybe the car ride to the ball, you can't remember the ball at all. Sometimes the little times you don't think are anything while they're happening turn out to be what marks a whole period of your life. I should have been dreaming for months about the car ride to the ball and getting dressed for the car ride, and buying my ticket to Europe so I could take the car ride. Then, who knows, maybe I could have remembered the ball.

Michael Robartes and the Dancer (1921)
Context: Opinion is not worth a rush;
In this altar-piece the knight,
Who grips his long spear so to push
That dragon through the fading light,
Loved the lady; and it’s plain
The half-dead dragon was her thought,
That every morning rose again
And dug its claws and shrieked and fought.
Could the impossible come to pass
She would have time to turn her eyes,
Her lover thought, upon the glass
And on the instant would grow wise.
