Since switching to GTD, I've removed most of my pre-planned blockers and it's working well. How is color coding helping with the fact that according to GTD, only actual appointments should be put into the calendar?
I have gotten good results from calendar blocking, so obviously I disagree with Davids rule about only putting things in the calendar that has to be done then. I can see his point for a physical calendar, but on a digital calendar you can have a (say) red calendar that your "must be done at this time or not at all" appointments can be added. That way when you see a red calendar entry you known what it means.
