It depends on the goal. Some of them I just need to be reminded about, others I need to track ‘30 minutes per day’ (or whatever) in order to get anything meaningful done.
Most of the time, I’m going to read more than one page, floss more than one tooth, and so on. But some days are unpredictably manic, and I’ll do the minimum, which is better than deciding to let a more ambitious goal derail. And of course I’ll get reminded again the following day…
I’m pretty good with spreadsheets, but every time I try to use a simple list or custom tracker, I forget to keep it up to date. At least with Beeminder I’ll be prompted to enter my data…
