Yep. By the time I get to actually writing the code, I feel relieved because by then I have a pretty clear idea of how I'm going to do it, and I can work quickly. It's the hours of figuring that out that are difficult, and the boss demanding constant progress reports when I'm still figuring it out and have nothing to show but a bunch of notes and TODOs. I find that writing my thinking notes in the form of documentation for the product can help appease management.
