I've setup a
Daily Action Review sheet (pdf) that I use to track the daily tasks I want to get done, and use LifeBalance on my PDA for the rest of my tasks.
I kind of diverge from GTD in that I assign a point value to each action (usually it's only 1, but for more effortsome tasks it's increased) as a means of goal setting. Each day I add up the points for my daily actions, and then add in points I've gained from completing Next Actions that day.
On Sundays, I do a 5-10 minute
Weekly Action Review sheet (pdf) where I look at my everyday actions and give myself bonus points for consistently completing everything on my Everyday Actions list. Then I look at where I'm doing well and where I can use some improvement, and make note of that for the coming week.
Once I reach 1500 points (it takes about a month or so), I reward myself with a bit of spending cash that I can put towards something on my wish lists.
I know it seems a bit involved, but once it's setup it's very easy to do. It's amazing how a simple piece of paper can add accountability to my daily routine.
I'm a student right now, working on a double major and a part time sales job, so it's geared towards that, but if anyone likes the idea and wants the original Illustrator .ai files to customize then I'll be glad to upload them.
