Some of my GTD implementations

First, I try to write down personal productivity ideas in a moleskine. It's color coded so that I can identify different categories quickly.



I also have a shoebox cover that I use as a tray for stuff I should take with me when I leave home.



Finally, I have a checklist for things I should be doing daily. These range from my work to health issues (e.g. going to the gym, eating fruit). I also record the fun things I do. If I see that I've spent my last week's free time on video games, I might try to do something different the next week.
