I finished reading GTD last week and a second reading last night. I can't believe how much this book has opened my eyes. I've been dealing with email at the office, at home and on the road. I faithfully use my Treo and still use my Franklin-Covey Planner...and I "thought" I was well organized.
I went into my office today when nobody except the cleaning crew was there and absolutely THRASHED my office. It took me nearly 9 hours to collect, process and organize. But it was EXHILARATING to see all that I accomplished...and how much PAPER I had unnecessarily burdened myself with.
Our firm makes heavy use of an intranet for scheduling, itineraries, project teams (product status, notes, files, legal, etc) and whatnot.
I normally tag stuff in my paper planner related to the intranet material...What are you all doing?
