I discovered Dave Seah's printable CEO series of tools and templates early in my working career (some 15+ years ago) and found them super practical and useful.
I have diligently used (my own variation of) his Emergent Task Planner for many years and it served me well.
I was proud of how organized I was. Kept years of daily planners as proof.Still have them in my attic I think.
Then life happened. Marriage, kids, moving countries, changes jobs, no longer an individual contributor but responsiblefor teams ... and sorry to report I fell of that productivity wagon. I wish and hope to get back into better daily routine. Maybe I should rediscover his tools and make them mine again.
