I ain’t no Stephen Wolfram but I do try to time myself on any activities I do on my computer whenever possible. Mostly to validate (or train my mind) the time took to finish a task is not what I thought it would be. At times I pleasantly surprised, most often my estimates are always under estimated.

I was cleaning up my mac before handing it to systems on my last job. I had a couple of days just for the Knowledge Transfer of projects and nothing else. I have always run two or three passive self policing apps like Rescuetime and Timing etc.,
