Now, here is what I would like to see: the OFF switch. Hitting a button that would block all electronic distractions (turning off television etc) and block distracting sites (like youtube/reddit/HN) and disable distracting apps (like iPhone games) for half an hour.
This most likely will involve special outlets or plugs that can be turned on/off via wifi.
Only one piece of the puzzle, but a big one.
One day I watched a talk by Tim Ferris and he mentioned the so called flash diet - in order to lose weight you take a picture of every meal you eat which is supposed to make you aware of your decisions that were previously habitual or subconscious and change your behaviour.
I realized this could also work when you are trying to fight procrastination. I created a little anti-procrastination tool based on that idea: http://www.simplyeasy.cz/war-on-procrastination. It's dead simple to use... all I have to do before I start wasting my time is to press the "pause" button. To my own surprise it really works for me. Tim Ferris might be on to something.
