I just switched jobs, and at my old company, we used Lotus Notes (yuck), but now I have Outlook 2003 (yay!) with wireless sync to Blackberry 4.1 (yay!). So what better time than to try to implement GTD in a fully electronic manner, right? I bought the “GTD for Outlook” whitepaper and have more or less set-up Outlook and my Bberry accordingly. I am relying utterly on wireless syncing between Outlook and my Blackberry, and I'm able to tolerate the somewhat clunky way of filtering by “category” in the default Bberry Task application. My main question is this: WHAT IS THE BEST WAY TO SEGREGATE "PERSONAL" LISTS FROM "PROFESSIONAL" LISTS, aside from the obvious, which is to set up @calls-personal, @calls-professional, @WaitingFor-personal, @WaitingFor-professional….which is a bit cumbersome (it's the way I have it set-up now). I know this segregation is not really encouraged in GTD, but realistically there are two spheres to my life: e.g., when I'm working, I care about what work-people owe me (@WF-prof), otherwise, I care about what my wife, family, friends, service-providers, etc. owe me (@WF-pers). I tried setting up a customized field called “Sphere” within Outlook, which would have two allowable values (personal or professional), but couldn’t figure out how to set up the 2 values, or how to group the views in Outlook….and furthermore, Blackberry wouldn’t have the field, so I wouldn’t be able to filter on the handheld…. Any ideas? I'd like to avoid buying fancier SW for the Bberry to accommodate this, but I'm not opposed as long as it integrates seamlessly and wirelessly with Outlook 2003. Thanks!
