answer:Massive article about this in NewScientist No2634 last week (15 December 2007) . Basically you just need to work during a time when you have nothing to do except work. Then remove every distraction like your computer, your phone etc. Throw your BlackBerry out the window and make a firm commitment to whoever wants whatever it is done. Then set reachable goals, don’t do all the work in one load because you will never even start (bah-bah… dah-dah bombombombom). The get someone to whip you into action and keep you going.
