Using Org-mode as a Day Planner

The following document describes how to use Carsten Dominik’s excellent
org-mode Emacs package after the fashion of a pen-and-paper day planner.

For those curious, I was not brought up on time management in the era of
the current GTD fad. I started with a hard-bound book filled with daily
planning sheets, along with training and books supporting this method. I
found it incredibly useful for the three or so years that I stuck with
it, but ultimately discovered that only digital media can truly keep up
with my ever-changing world. Thus began my quest for the ultimate,
computer day planning package.

I spend most of my day working on or near a computer:  writing, replying
to e-mail, making phone calls, and so on. I use Lotus Notes for my
calendar because people need to be able to check my availability for
meetings. I use Emacs to keep track of what I need to do, because it
makes planning my day so much easier.
