Last week I didn't do my weekly review and this weekend I did it 2 days late. That means I was 9 days late with my weekly review - the last time I did my weekly review was 16 days ago. In the last few days, I noticed that I started slipping. I didn't have a full grasp on what my active projects entailed anymore. My context lists started to look a bit foreign to me. I had been working on some customer projects with deadlines, which meant that my other projects were pushed a bit in the background, although I did work on some here and there.
I noticed though that the Weekly Review allowed me to become aware again. Many may be able to wait this long between reviews, but I'm obviously not one of them. I did learn though that I had learned a new habit last year - the weekly review.
