I did this, or close enough. I fastidiously added lots of small tasks, and any time I had a few minutes, or a half hour, I would scan through and find something doable and check it off. I got a LOT of stuff done. I also added the larger things, so I could keep track. The only downside is that there were larger things that I couldn't break up into smaller things without getting deeper into it. It was too easy for me to put those off (because I didn't have a solid block of time) and just complete several smaller items. The large items started to pile up, to my detriment. I'm not trying to say there aren't ways to deal with this. There are. I was still exploring such ways when I recently took a job where I once again have decent blocks of uninterrupted time in a quiet environment.
