Remove as many visible clocks from your life as you can, to break your clock obsession.
Rely on alerts, rather than clock-watching, to coordinate meetings and appointments with others.
Use new apps and online tools to match tasks with timers.
Make sure you can easily pause the timers for distractions and interruptions (which you should try to minimize).
Optimize your use of time by flexibly tweaking tasks and the time allotted to those tasks.
Use mobile and online tools to constantly focus on the actual achievement and completion of tasks and goals.
It's time to start phasing out clocks as the dominant context of our lives and our work. We have better tools now. And by taking advantage of them, we can lower stress, raise productivity and -- finally -- get things done.
