Here's a nifty little idea from Buster McLeod for writers:
I've long been inspired by an idea I first learned about in The Artist's Way called morning pages. Morning pages are three pages of writing done every day, typically encouraged to be in "long hand", typically done in the morning, that can be about anything and everything that comes into your head. It's about getting it all out of your head, and is not supposed to be edited or censored in any way. The idea is that if you can get in the habit of writing three pages a day, that it will help clear your mind and get the ideas flowing for the rest of the day. Unlike many of the other exercises in that book, I found that this one actually worked and was really really useful.
750 Words is just that: A site for you to write 750 words a day. It's not blogging, it's not for public consumption, it's just for you to write. Your score increases the more days in a row that you write, and you can share your score with the world if you like. There's apparently an algorithm that will tell you your mood, too—"I use a text-analysis system called the Regressive Imagery Dictionary to calculate the various emotional content of each day's entry," he writes—which is nice in a horoscope-y sort of way, but the most important thing about this site, by far, is the writing. Read the FAQ and get started.
