I journal sporadically. I find the act helpful to work through ideas, problems, and challenges. I came across 750 Words a while back on Lifehacker and I've been thinking about it off and on.
Here's 750 Words curator, Buster Benson, to tell you what it is:
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.
I've used the exercise as a great way to think out loud without having to worry about half-formed ideas, random tangents, private stuff, and all the other things in our heads that we often filter out before ever voicing them or writing about them. It's a daily brain dump. Over time, I've found that it's also very helpful as a tool to get thoughts going that have become stuck, or to help get to the bottom of a rotten mood.
Buster loves his infographics.
Personally, I don't think I'll take this one on. I have too many deadlines as it is, I don't need another daily one.
I've started microjournaling recently, though. I use a little app called Momento on my iPod Touch to capture quick little Twitteresque notions. I figure I'll save my loyal followers the trouble of scrolling past my more idiotic or mundane ramblings.
