I have been trying to implement GTD for the last 6 months and am seeing huge benefits in my productivity and ability to move things forward. I have read David's 3 books, although I know that I still have work to turn this into free-flowing habit and get the most value out of this.
I have the opportunity to go to one of the public seminars in London over the next few months, though getting the more expensive one charged through the company could be more tricky.
Can anyone recommend which of Mastering Workflow and Making it All work, I should aim to try to get on to? Any feedback on the seminars would be welcome
