I’ve been testing out RescueTime, a service that tracks and plots your computer usage. The idea is that it’ll give you an idea of what’s wasting your time.
You install a small app and let it run. Every few minutes, it uploads usage stats to www.rescuetime.com, which you can access at any time to check out your usage. It’ll also email you a summary every week.
I used it for a few weeks, and to my surprise I learned nothing new. I know what I spend most of my time using (Safari and the terminal, mostly). I know what wastes my time (YouTube and Fark, mostly, which I’ve now blocked).
It was a worthwhile experiment, though, and you might want to give it a try if you’re curious about how you spend your time. It certainly functioned well.
