One of the downsides of being organized and having a clear picture of everything you need to do is that you realize just how much stuff you need to do! I've been using David Allen's GTD method a lot lately, along with the help of an application called OmniFocus, and I can't believe how much stuff I have written down since I started using this method. I have 300+ items in OmniFocus. Try to imagine the relief and freedom I have given my brain by allowing it to let go of trying to remember (subconsciously) 300+ items and you'll begin to see why the GTD method is so powerful.
For implementing GTD you can use this web-based application:
http://www.Gtdagenda.com
You can use it to manage your goals, projects and tasks, set next actions and contexts, use checklists, schedules and a calendar.
A mobile version and iCal are available too.
Maybe I should use something like that. I’m often reminded by the wife of pictures that I haven’t printed for her from 2 or 3 years ago. 😕 I have no idea what pictures they are and she won’t tell me.
