How to write.
In learning to write, our first rule is: Know what you want to say. The second rule is: Say it; that is, do not begin by saying something else which you think will lead up to what you want to say. Thirdly, and always: Use your own language. I mean the language you are accustomed to use in daily life. If your every-day language is not fit for a letter or for a print, it is not fit for talk. And if, by any series of joking or fun, at school or at home, you have got into the habit of using slang in talk which is not fit for print, why, the sooner you get out of it the better.
Remember that the very highest compliment paid to anything is paid when a person hearing it read aloud thinks it is the remark of the reader made in conversation. Both writer and reader then receive the highest possible paise.
