No More Learning

But an experience--(and I should not need           in abundance
to prove my words, if I added)--a tried experience of twenty years, has
taught me, that the original sin of my character consists in a careless
indifference to public opinion, and to the attacks of those who
influence it; that praise and admiration have become yearly less and
less desirable, except as marks of sympathy; nay that it is difficult
and distressing to me to think with any interest even about the sale
and profit of my works, important as, in my present circumstances, such
considerations must needs be.
