Who knows where inspiration comes from. Perhaps it arises from desperation. Perhaps it comes from the flukes of the universe, the kindness of the muses.
— Amy Tan

Thus, with child to speak, and helpless in my throes, biting my truant pen, beating myself for spite: Fool! said my muse to me, look in thy heart, and write.
Sir Philip Sidney musing quote

The most potent muse of all is our own inner child.
— Stephen Nachmanovitch

Perversity is the muse of modern literature.
— Susan Sontag

Then this immensive cupOf aromatic wine,Catullus, I quaff upTo that terse muse of thine.
— musing quotation by Robert Herrick
