I find this to be generally true. I used to think i was just working too hard in the early part of the day, burning myself, and simply needed to take breaks. Its true to an extent, but generally speaking I find I have a "window" where I can get meaningful work done, usually between 9-3. Some days its really long, some days it doesn't exist at all, but most days its about 4-6 hours. I either pad the extra time (and feel like I'm doing something wrong) or stress out trying to be more productive. But in reality, I think the window is simply how creative effort works. Though my current office is pretty good about this in general, I wonder if more companies could embrace it would we develop patterns to maximize and plan around these effectivity windows.
