Fiction pays best of all and when it is of fair quality is more easily sold. A good joke will sell quicker than a good poem, and, measured in sweat and blood, will bring better remuneration. Avoid the unhappy ending, the harsh, the brutal, the tragic, the horrible - if you care to see in print things you write. (In this connection don't do as I do, but do as I say.) Humour is the hardest to write, easiest to sell, and best rewarded... Don't write too much. Concentrate your sweat on one story, rather than dissipate it over a dozen. Don't loaf and invite inspiration; light out after it with a club, and if you don't get it you will nonetheless get something that looks remarkably like it.
'Getting into Print', first published in 1903 in The Editor magazine
