I alternate - but discovered my perception of productive days can be skewed. I came from physical, real world jobs like construction. When my day was done, I had something tangible for my efforts (fence, concrete, brick wall, etc.) When I started in computer work, some days I felt super productive, but others I didn't. On many of the days, I didn't feel productive. I was still brain dead from the work on these 'less productive' days. Back in those days, I printed a lot of stuff. I discovered that I felt more productive on the days I printed more things, because printed pages are tangible items. On the days I felt less productive, I was still doing a ton of work, but the lack of tangible evidence skewed my perception.
