I love gadgets and technology. Always keen to try the latest and greatest. I had an all electronic GTD system involving MS Exchange, Outlook Web Access and a BlackBerry. Technically it all zinged along and I could access my lists any time, anywhere. Problem was I was going numb to them and not actually getting as much done as I wanted. I wasn't comfortable with what I wasn't doing. So I decided to give paper a try. I created a hybrid system where my calendar remained in Outlook (and therefore on my BlackBerry too) but I moved my Next Action and Project lists to a Moleskine Cahier.
I just finished a 30 day trial and my wrap up is here:
Along the way I documented observations - what was working, what wasn't.
Although everyone's circumstances are different I hope you find it of interest.
