“We can so easily slip back from what we have struggled to attain, abruptly, into a life we never wanted; can find that we are trapped, as in a dream, and die there, without ever waking up. This can occur. Anyone who has lifted his blood into a years-long work may find that he can't sustain it, the force of gravity is irresistible, and it falls back, worthless. For somewhere there is an ancient enmity between our daily life and the great work.”
