Rules for Writing--P. D. James

1 Increase your word power. Words are the raw material of our craft. The greater your vocabulary the more ­effective your writing. We who write in English are fortunate to have the richest and most versatile language in the world. Respect it.

2 Read widely and with discrimination. Bad writing is contagious.

3 Don't just plan to write – write. It is only by writing, not dreaming about it, that we develop our own style.

4 Write what you need to write, not what is currently popular or what you think will sell.

5 Open your mind to new experiences, particularly to the study of other ­people. Nothing that happens to a writer – however happy, however tragic – is ever wasted.
