Do not wait to strike till the iron is hot; but make it hot by striking. - William Butler Yeats

One should say before sleeping: I have lived many lives. I have been a slave and a prince. Many a beloved has sat upon my knee and I have sat upon the knees of many a beloved. Everything that has been shall be again.

A line will take us hours maybe;
Yet if it does not seem a moment’s thought,
Our stitching and unstitching has been naught.
Better go down upon your marrow-bones
And scrub a kitchen pavement, or break stones
Like an old pauper, in all kinds of weather;
For to articulate sweet sounds together
Is to work harder than all these, and yet
Be thought an idler by the noisy set
Of bankers, schoolmasters, and clergymen
The martyrs call the world.

Life is a long preparation for something that never happens.
