How to do a daily review: the 5-minute end-of-day practice that compounds over time
A daily review takes 5 minutes and produces 23% better performance over 10 days (HBS, 2014). Here's exactly how to do one using today's reflection and friction tools.
What a daily review actually is (and isn't)
A daily review is a 5–15 minute end-of-day reflection on what you planned, what you did, what worked, and what to carry forward. It's not a performance evaluation, a journaling session, or a project update. The purpose is to convert each day's experience into extractable learning that improves tomorrow's decisions. The Harvard Business School study that validated this practice gave participants 15 minutes of structured reflection at the end of each call center shift. After 10 days, the reflection group outperformed the control group by 23% on a learning assessment. The mechanism is clear: deliberate reflection transforms experience into learning; unreviewed experience mostly doesn't.
The 5-minute daily review sequence
Open your daily planner. Look at your planned outcome — did it happen? Mark it complete or note why it didn't. Review your time blocks: which ones were used as planned, which were disrupted? Log your primary friction source (what slowed you down most today). Write 2–3 sentences in your reflection: one thing that went well, one thing you'd do differently, and one thing to carry to tomorrow. Close your planner with these completed. That sequence covers every essential element of a daily review in under 5 minutes if done without distraction.
How to review your commitment streaks
The last piece of an effective daily review is commitment evaluation: for each commitment you're tracking, mark it kept or broke honestly. This takes 30 seconds. The 'broke' marking is the most important: it's information rather than a failure. A commitment marked broke three times in a week tells you either the commitment needs to be redesigned, the enabling conditions aren't in place, or the commitment isn't actually important enough to maintain. Honest marking is what gives the system validity — commitments tracked with self-deception produce no useful data.
What to do with your daily review data over time
Individual daily reviews are valuable; accumulated daily reviews are powerful. Once per week (Friday afternoon or Sunday evening), read your last 7 days of reflections in sequence. Patterns emerge that are invisible in single-day reviews: recurring friction sources, consistent energy patterns, habitual planning mistakes, recurring win conditions. A monthly review of 30 daily reflections produces insight at yet another level — quarterly progress toward goals, seasonal capacity patterns, the effectiveness of process changes you've made. The daily review is the raw data feed; the weekly and monthly reviews are the analysis layer.
