3, 2, 1, write! The One Minute Writer's headline explains it all; "You Have 1,440 minutes a day. Use one of them to write."
How it works: Head on over to The One Minute Writer. Read the daily writing prompt. Click "start" on the 60-second timer. Then, be brilliant. Quickly.
For those of you who don't think you have time to write daily, here is your answer. With prompts ranging from: "A new Broadway musical is about your life. Come up with a title for the big show, and write a mini-review of it" to "Take on the fictional persona of a beauty pageant contestant" to "Listen. Write about what you hear, right now," there's all kinds of ideas to get the juices flowing. Once you've written for your minute, you can also read what other writers have posted in response to the prompts.
A daily trek to The One Minute Writer is a minute (or many more) well spent.
