I'm sure this idea will help some people become more productive. Not people like me, though. Maybe I just get easily distracted, but I make small deals with myself when working through a mundane (but important) task.
Deals like:
- "15 more minutes and you can get a coffee".
- "You can't look at HN until 4pm".
- You get the picture.
A clock helps immensely with this. Sometimes a task feels like it's taking forever, but it's only been half an hour.
