Since I seem to be on the roll with encouraging posts this week (and why not? you guys are forever giving me phenomenal encouragement), I thought I'd give another good chunk from Steven King's On Writing.
You can approach the act of writing with nervousness, excitement, hopefulness, or even despair--the sense that you can never completely put on the page what's in your mind and heart. You can come to the act with your fists clenched and your eyes narrowed, ready to kick &$! and take down names. You can come to it because you want a girl to marry you or because you want to change the world. Come to it any way but lightly. Let me say it again: you must not come lightly to the blank page.
I'm not asking you to come reverently or unquestioningly; I'm not asking you to be politically correct or cast aside your sense of humor... This isn't a popularity contest, it's not the moral Olympics, and it's not church. But it's writing... not washing the car or putting on eyeliner. If you can take it seriously, we can do business. If you can't or won't, it's time for you to close the book and do something else.
Wash the car, maybe.
