What do you mean--that you have been working, but without success? Do
you mean that you cannot get the price you ask? then sell it for less,
till, by practice, you shall improve, and command a better price. Or do
you only mean that you are not satisfied with your work? nobody ever was
that I know, except J---- W----. Peg away! While you're at work you must
be improving. Do something from Nature indoors when you cannot get out,
to keep your hand and eye in practice. Don't get into the way of working
too much at your drawings away from Nature.
_Charles Keene._
