For I think it truth that a life uncommanded now is uncommanded; a life unenjoyed now is unenjoyed; a life not lived wisely now is not lived wisely: for the past is gone and no one knows the future.
a.1900, T. Bailey Saunders, M.A., Counsels and Maxims[2]:
A thousand gay and pleasant hours are wasted in ill-humor; we let them slip by unenjoyed, and sigh for them in vain when the sky is overcast.
