Personal unit tests

As an increasingly serious practitioner of David Allen's Getting Things Done (GTD) system, I immediately appreciated this post on 'personal unit tests'. I think 27 daily tests is probably far too many to begin with - this might explain the author's 85% failure rate.... but then again, think of the glow of satisfaction he'll experience when he passes all 27! I think this appeals to me in the same way that GTD does - one real lesson from which is to keep taking the small steps.... Found via Phil Wilson's blog.
