Excerpt from The Art of Worldly Wisdom by Baltasar Gracián.

lxxxi Renew your Brilliance.

’Tis the privilege of the Phœnix. Ability is wont to grow old, and with it fame. The staleness of custom weakens admiration, and a mediocrity that's new often eclipses the highest excellence grown old. Try therefore to be born again in valour, in genius, in fortune, in all. Display startling novelties, rise afresh like the sun every day. Change too the scene on which you shine, so that your loss may be felt in the old scenes of your triumph, while the novelty of your powers wins you applause in the new.
