Not really myself but because I already have a separate study log. I’ve had a couple of months of trial and error since I started, and recently came to realise that I’ve been doing better with open and relaxed schedules. I don’t have fixed goals (other than daily SRS reviews), so I don’t feel bad when I don’t complete them, and since I don’t feel bad I end up doing more than when I did impose myself some goals. I have it divided in different categories like reading, listening, grammar… and I just log what I do. As long as I’m doing something every day or at least every week I’m happy about it, it means I’m moving forward. And I can see that visually when the week ends and I see what I’ve logged. The main/summary posts everyone is doing here has the same effect I’m sure. You get to see in the form of checkboxes or whatever how long or how much you did. These are specially useful when you’re feeling down or having a week where you don’t do much; it doesn’t bother as much.
So for this reading challenge it’s more the same, I just log here what I read everyday, as well as in the study log with the rest that I do. I like the relaxed nature of it, “no goals just read” (which ironically is a goal itself).
This mindset can potentially attract heavy procrastination as well though so I’d say try different approaches ^^ .
