I started using checklists for my daily tasks some years ago. I did it so I wouldn’t have to rely on my memory to remember everything. I tried to use 42goals.com to do it for a while in 2012, but the site didn’t work well on mobile at the time, and I dropped it after some months. This recent “streak” of tracking my daily tasks using a checklist began at the end of last August.
In the beginning, I just made a list of every one of my daily actions, including things like going to the bathroom, or drinking water. Then I refined the process by taking some unnecessary actions out of it (I was always a heavy water drinker, and tracking my trips to the bathroom wasn’t exactly achieving any goals).
