To be happy is only to have freed one's soul from the unrest of unhappiness.

We should tell ourselves, once and for all, that it is the first duty of the soul to become as happy, complete, independent, and great as lies in its power. Herein is no egoism, or pride. To become effectually generous and sincerely humble there must be within us a confident, tranquil, and clear comprehension of all that we owe to ourselves.

You can't write masterpieces in your 80s and be happy too.

Just try to be happy. Unhappiness starts with wanting to be happier.

They think the banjo can only be happy, but that's not true.

And it is because we all of us know of this sombre power and its perilous manifestations, that we stand in so deep a dread of silence. We can bear, when need must be, the silence of ourselves, that of isolation: but the silence of many - silence multiplied - and above all the silence of a crowd - these are supernatural burdens, whose inexplicable weight brings dread to the mightiest soul.
