To read my complete journey to GTD Mastery see the main post.
Step 7 to GTD Mastery is: I always have a way to capture ideas and get them out of my head, in all contexts.
My HipRock serves as my ubiquitous capture tool (UCT).
It’s created using the PocketMod report from Thinking Rock.

You can then customize the layout of where you want the new thoughts section for the printout seen below.

The HipRock is printed on a standard sheet of 8.5×11. It’s folded in half width-wise and into quarters length-wise for structured viewing of my NAs, project list, and new thoughts. The folding makes it easily pocketable. Add your writing instrument of choice and it’s ready to go.

I’m really liking Jott (Jott.com) for capture. It’s a phone to text service that lets you take voice notes and transcribes them into your inbox. Best of all, it’s absolutely free (it’s an 800 number) and works nicely with Vitalist.
I tested out Jott+Vitalist too, but I’m on a pay-as-you-go cell-phone plan and all that Jotting I know would cost me a lot of money =P
something for everything…
