When I first did a chemistry class in high school, this was the first thing they taught us. At the time I thought it was the most boring pointless thing ever. Of course now I realise how important it is in academia and industry (to have evidence of the discovery process) and while I don't have to do this or follow it exactly, I do approximate to this and have found it very useful. It's also the only useful thing I took out of chemistry class as I was a terrible student :)
In addition to that, I now keep an open text editor tab with the following items and update it several times a day:
An in-progress list
A todo list
A "blocked" list
A "done" list (sections for each week)
That works pretty well for me.
