I’ve been working through the Learning How to Learn course on Coursera, and one of the things the teachers recommend is using the Pomodoro Technique. When I first heard about it it sounded too simple to work, but you know, it’s actually really helpful. I personally have trouble getting started on tasks in part because I feel like it’s going to take all day to get it done and I just don’t wanna :) The Pomodoro Technique helps me because there’s a built-in stop time – when 25 minutes are up, it’s time for a break.
The Pomodoro timer I use is tomato-timer.com. I can’t say I really need another tab open all the time (if I counted correctly I have 42 tabs open right now), but it’s super easy to use and I like not having to install anything. If you have trouble getting started or staying focused, give it a shot. It can’t work any worse than what you’re already doing :)
