I was (and still am) an extremely social person. Having the discipline of keeping on schedule, and beating deadlines has made me actually work (that's a joke). When you are not surrounded by other social people, you would be surprised at the work that you can accomplish.
I don't think I ever want to go back to an office setting again, my home office suits me fine.
I work for a global company and my direct reports span many timezones. I start at 0600 when my EU reports are already at work and often go until 1800 or later when my AP report comes online.
Corporations would get so much more out of their employees if they focused on actual work completed rather than the numbers of hours occupying a chair.
That said, teleworkers must be appropriately managed and have self-discipline and integrity.
