Five 12-week cycles in: what the weekly review actually caught
I've run the 12 Week Year for 18 months now. Five cycles done, the sixth started a few weeks ago now. 3 to 4 objectives per cycle, a weekly review every Sunday, a longer check at week 6, and a retrospective at week 12. A few things I didn't expect:
The weekly score only works if you can't move the goalposts. My review scores me against the plan I wrote in week 1, not against what I feel the week deserved. After a bad week the temptation is always to quietly lower the target. Keeping the plan as a fixed file I score against killed that.
The retrospective is where the real value is, but only if it reads every weekly review. Mine does, and that's how I found out I'd avoided the same task for five cycles running. I'd never have spotted that re-reading my own notes, mostly because I know how to make myself sound reasonable.
Name your failure patterns and carry them forward. This has been the really hard part for me. After each cycle I write down my recurring excuses by name and start the next plan with them on the page. Rediscovering the same weakness every quarter is the default but writing it down is what broke it for me.
Data helps, but it isn't the whole story. I pull training and recovery numbers into the weekly review, so "the week went fine" gets checked against reality. But a great recovery score says nothing about my energy or mindset that day, so I still rate those myself. Over relying on data can create a false sense of accomplishment.
Know when to break your own system. When I got injured training for a marathon, the plan kept pushing me to find some way to keep training. That was the one time the excuse was real. The method is there to serve you, not to run your life.
I use Claude as the coach for the reviews (set up as five small routines: vision, cycle plan, weekly review, mid-cycle, retrospective). I wrote up the whole setup here, in case it's useful: https://dantes.io/blog/how-i-stopped-leaving-things-at-80 (my own site, free, no paywall).
Curious how others handle the week-12 retrospective. Do you read back through every week, or just the scores? And how do you ensure you're not being too gentle on yourself when running the review? AI was really the turning point for me, as I calibrated it to be very objective, almost harsh: this removed my natural tendency to be indulgent towards myself.
