One's days were too brief to take the burden of another's errors on one's shoulders.
Cujusvis hominis est errare, nullius, nisi insipientis, in errore perseverare.
One tiny mistake can't ruin something that good.
Promise me, if I cave in and break,
And leave myself open,
That I won't be makin a mistake...
Although you're at the top, if you make one small mistake, it's easy to fall right down.
