- Noise cancelling headphones work as well at home as they do at work. I love mine.

Anyway, person-to-person and day-to-day differences in productivity are pretty large in my experience. Of course you could be in a bust-your-butt-for-a-promotion kind of situation, but you could also take the attitude that you're getting paid for what you actually do, and the fact that you are not top 1% productivity is reflected in your current "help-at-home-when-I-am-needed" salary.
