Oh, come on! Don't you have meetings to go to? How can you possibly have time to code eight hours a day if you have to work with other people?

Perhaps you're more fortunate than I in that your management effectively shields you from tasks outside the coding/development sphere. Perhaps the difference is that I and my co-workers jobs are more along the lines of "maintenance programming" than "new development". We have bugs to fix, users to keep happy, and management to appease. We have the company's ducks to put in a row (and then shove them into a database).

If I were in a different situation, I might be able to answer your question...   :-)
