If you would improve, submit to be considered without sense and foolish
with respect to externals. Wish to be considered to know nothing; and
if you shall seem to some to be a person of importance, distrust
yourself. For you should know that it is not easy both to keep your
will in a condition conformable to nature and (to secure) external
things: but if a man is careful about the one, it is an absolute
necessity that he will neglect the other.
