Me too Wolf, especially when going to busy places I prepare some work, perhaps look at some 'masters'. It does help me a lot to ignore the massive ammounts of people, details, whatever that you'll run into and get you to focus on specific stuff. Not that I use it as a restriction, but when I don't I always think "Oh, if I did this or that, this would be been an awesome photo - why didn't I see that at that moment ?". :)
