Greetings to the 43F Board...

This is my first post to the board. Thanks to all who do post regularly, I have learned a great deal just from reading about all the different ways of implementing GTD.

I am currently using the Hipster PDA to manage projects and next actions (calendar events / contacts are kept on my cell phone's PIM). Each project is kept on a card with next actions & project support info listed on the card (very similar to how Emory uses index cards).

Out of curiosity, I was wondering out of those with a paper based system of project tracking (hipster or otherwise)...how often do you review your projects for next actions? I know the standard GTD answer is "during the weekly review", but are there those who review more frequently in order to stay on top of high-priority projects and ensure that there is a next action on the list?

If so, what triggers you to review? If you are having to remind yourself to scan your projects before the next weekly review, then how do you keep the "mind like water" state?

Thanks for any info you can send my way.
