Gina Trapani, of Lifehacker, wrote about Practicing Simplified GTD (Getting Things Done) today that really struck a chord:
"David Allen's complete GTD methodology, as he writes it, is still an elusive ideal for me. I regard it kind of like I do Buddhism: a big, mysterious, and wondrous way of living and thinking that you really want to get, because the people that have seem so bright and fulfilled. But you keep falling on your ass no matter how many inboxes you set up or mind dumps you do. The perfect is the enemy of the good, as the saying goes, so instead of giving up on GTD completely, take the parts that work for you and work them."
I'd love to completely adopt GTD, but it's never 100% for me.
As much as I'd like it to be, it's like exercise - you are better off for doing it and should feel good that you do what you can, when you can.
