[gramie]

I went through a period of a couple of months where I pair-programmed almost every day, and it was probably the most productive time of my career. My partner was very junior, and new to the project, and the process of explaining things to him definitely helped avoid some of my blind spots. He had several good insights and ideas, too, coming in with fresh eyes.

It was high-energy, though, and an extended period might well have been fatiguing.
