This one was a lot more “worked” than “inspired.”  I am sure there is a quote for that.  Oh, here’s one:

Inspiration is wonderful when it happens, but the writer must develop an approach for the rest of the time… The wait is simply too long.
-Leonard Bernstein (1918 – 1990)

For the curious:

The wisdom of the wise, and the experience of ages, may be preserved by quotation.
-Benjamin Disraeli (1804 – 1881)

We don’t receive wisdom; we must discover it for ourselves after a journey that no one can take for us or spare us.
-Marcel Proust (1871 – 1922)

Wise men talk because they have something to say; fools, because they have to say something.
-Plato (427 BC – 347 BC)

To forget one’s purpose is the commonest form of stupidity.
-Friedrich Nietzsche (1844 – 1900)

Hope is tomorrow’s veneer over today’s disappointment.
-Evan Esar (1899 – 1995)
