Perhaps these aren't the correct terms, but I do feel an entirely new sensation while coding now than just a week ago. The big difference is that before I could essentially dive into whatever I was going to work on and hack away. Perhaps I break something along the way, but I'm in the zone and that's OK I'll go back and fix it. Now however, it's entirely different. I find myself tiptoeing through the code to avoid creating new bugs while fixing the existing ones. It's good to recognize that I shouldn't create new bugs :-), but it's just an odd sensation.
