You Know You've Got GTD When...

you start living your life by contexts
you know what a "UCT" is [Ubiquitous Capture Tool]
you write / type every thing down into a "trusted" place
the only things on your calendar are hard landscape things that you absolutely must do that day (or you / it will die)
you re-read the GTD book every year
you have bought or you are considering buying the David Allen Notetaker Wallet (with the really cool pen)
you've done at least five complete mind-sweeps
you've tried every GTD type app available for your phone /computer / laptop / tablet
you have a saved search for "GTD" in your browser and in Twitter
you no longer segregate your life between work and home
you not only do weekly reviews, you now do mini daily reviews
you ask yourself "what is it? Is it a project?" 700 times per day
you've got a "Someday / Maybe" file (in Evernote)
you have started a "tickler file"
you always have something to do where ever you are - you just check your contexts
you know who Merlin Mann is and you practice "InBox Zero"
you are stress free and you feel in control.
