I wrote this yesterday, but I am just getting to post this today.
Dorothea Brande offers some advice on Becoming a Writer. There is much wisdom in the book, but one of the most helpful pieces of advice she offers is on page 74. How to learn to write with more ease.
The best way to do this is to rise half an hour, or a full hour, earlier than you customarily rise. Just as soon as you can—and without talking, without reading the morning’s paper, without picking up the book you laid aside the night before—begin to write.
Write anything that comes into your head: last night’s dream, if you are able to remember it; the activities of the day before, a conversation, real or imaginary; an examination of conscience. Write any sort of early morning reverie, rapidly and uncritically. The excellence or ultimate worth of what you write is of no importance yet. As a matter of fact, you will find more value in this material than you expect, but your primary purpose now is not to bring forth deathless words, but to write any words at all who are not pure nonsense.
I followed her advice yesterday morning (and this morning). I wrote for twenty minutes as I boiled tea in the early hours. When I got to editing my own book, I worked for two pleasant hours.
The advice to write first thing is given elsewhere, but Brande offers self-help for writers finding it hard to write.
