Our character is not so much the product of race and heredity as of those circumstances by which nature forms our habits, by which we are nurtured and live.
Any man may make a mistake; none but a fool will stick to it. Second thoughts are best as the proverb says.
[Lat., Cujusvis hominis est errare; nullius, nisi insipientis, in errore perseverae. Posteriores enim cogitationes (ut aiunt) sapientiores solent esse.]
