I used to be a huge advocate of GTD, and I’m still a moderate advocate of it, but I’ve found it not so helpful in times where I am overcommitted or overloaded. It’s hard to spot being in that state, and it can be mistaken for being unproductive. GTD is built on the idea of processing your inputs and distilling them into next actions, but when your inputs start arriving faster than you can process them, and you start doing email over the weekend just to keep your head above water, and you find all your time is being spent curating that list of actions but not actually doing them... at that point, you need more than GTD - you need traditional management skills like delegation and negotiation and organizing people to take over those responsibilities.
