If I remember right, John August recommended something similar, but fifty minutes (like a shrink) using an egg timer, he does fifty minutes work, then ten minute breaks ...

I jumped on Amazon and found some cheap timers - in everything from tomatoes to eggs to "fat chefs" - but they all tick... which is cool when cooking but not writing. So I downloaded the app and love it. You can change the amount of time it is set for and control whether or not it ticks. Like Scott, I like to get into a draft and work for hours uninterrupted, but there's another great use for this app timer... putting a limit on the time you spend on the Internet! Since I've got 21 minutes of internet left this morning, I'm going to mosey on to the next site....

I'm using this right now! Awesome! :)

Think this is a great tool for prep!
