Critics are by no means the end of the law. Do not think all is over with you because you articles are rejected. It may be that the editor has his drawer full, or that he does not know enough to appreciate you, or you have not gained a reputation, or he is not in a mood to be pleased. A critic's judgment is like that of any intelligent person. If he has experience, he is capable of judging whether a book will sell. That is all.
Regard your good name as the richest jewel you can possibly be possessed of for credit is like fire when once you have kindled it you may easily preserve it, but if you once extinguish it, you will find it an arduous task to rekindle it again. The way to gain a good reputation is to endeavor to be what you desire to appear.
