I don't have any goals set. I do at least 12 a month and beyond that, I do as many as I can. Toward the end of the month, I get busy doing summaries (which I should spread out throughout the month but don't) and my reviews stall. I like to do about 15 or 20 a month but sometimes I don't hit it. Other times I do a lot more. I'm getting bored with the stuff I write about and am looking around the house to see what I can review that's out of my zones.
