I just read a really great article by Augusto Pinaud on GTD Times, entitled "When you feel like you are losing control & lacking perspective."
It resonated with me particularly as I have really struggled with implementing my GTD system at home. At work I have found implementation has fitted well into my professional life and made an enormous difference to the way I organise myself and keep track of my commitments. However, I have found rather a barrier in my home implementation. I have tried to bring my ideas home and in some areas it has worked (for example, I no longer have an large pile of paperwork cascading across the dining table), but the sense of ease that I have with my professional work (most of the time) has been hard to come by at home.
The fact that Augusto also found it difficult to bring GTD into his personal life has allowed me to be less hard on myself and given me a spur to work at it more. Let the journey continue!
