Not obsessed, no really, I'm not, promise

Last night I spent way too much time frogging back on my preemie baby blanket. I did not see the mistake until I had several inches of knitting done, so I just ripped it out and started from where I made the mistake. I'm wondering if others do this as a matter of course. I mean, if it's a small mistake and you've really knitted too far past it, would you go back? In my case, it was a mistake that stuck out like a sore thumb and I could kick myself because I did not look at my work closely enough or often enough to catch it, which leads me to my next question--How many knitters out there look at their work closely? Do you review it every row, or every two rows or not at all? I guess I'm just wondering about how often it is that knitters go back and "refine" (ahem) their work. It probably depends on our basic nature--perfectionists will probably be reviewing their knitting constantly where others may tend to be more lax. But, aye, here's the rub--I am a perfectionist type but tend to not see my knitting mistakes, and I admit I don't look at my work as often as I should. I think I may become mesmerized (or meditative, if you prefer) and forget when I last looked. OK, this is beginning to sound like I'm obsessed, and I'm really not. It's just a question out there for you to think about and respond to.
