I wanted to highlight an excellent posting by Leo over on zenhabits.net on the subject of creating daily and weekly review routines.
I disagree somewhat with Leo’s assertion that David Allen leaves out structure from his Get Things Done (GTD) philosophy, personally I found it highly structured; but perhaps that’s just my mind imposing my structure on it, as Leo has done in his article.
Anyway, give the posting a read, I’m sure you’ll find it useful.
