Pink Floyd “There’s someone in my head, but it’s not me.”

"It is easy to take credit after an idea strikes you, but in fact, neurons in your brain secretly perform an enormous amount of work before inspiration hits."

"a thing is brought forth which we didn't know we had in us,

so we blink our eyes, as if a tiger had sprung out

and stood in the light, lashing his tail."

"our house is open, there are no keys in the doors,
and invisible guests come in and out at will.”

" poems should be written rarely and reluctantly,
under unbearable duress and only with the hope
that good spirits, not evil ones, choose us for their instrument."
