The Pomodoro method has changed my life! Whenever I'm writing or working out a creative problem, it really helps me focus on just one thing at a time. It's a simple timer that breaks down your day into 25-minute chunks (with 5-minute breaks). I use the Tomato One app on Mac OS, but there are countless others. Check it out and let me know what you think. I'd be happy to walk you through it or give some more tips if you need them. Thanks!
