Finish each day and be done with it. You have done what you could. Some blunders and absurdities no doubt crept in; forget them as soon as you can. Tomorrow is a new day; begin it well and serenely and with too high a spirit to be encumbered with your old nonsense.
Assuming, as you grow older, that you're the guardian of the world's wisdom, even if you haven't necessarily lived enough to know what's right and wrong.
Anyone can carry his burden, however heavy, until nightfall. Anyone can do his work, however hard, for one day. Anyone can live sweetly, patiently, lovingly, purely, until the sun goes down. And this is all that life really means.
Love is most nearly itself
When here and now cease to matter.
Old men ought to be explorers
Here or there does not matter
We must be still and still moving
Into another intensity
For a further union, a deeper communion
Through the dark cold and the empty desolation,
The wave cry, the wind cry, the vast waters
Of the petrel and the porpoise.
