Something I can add to user testing.

Like the title says, I'm looking for a small daily routine that I can add to user testing that will add up by the end of the month. I know I'm not going to get something as good as user testing, but is there anything in the ballpark of $5 for 20-30 minutes of work a day? I'm already doing a textbroker article or two each day, plus user testing when I can get it. I'm hoping for something extra to tack on to my routine.
