That's the most important part — that it be specifically for work. I'm a big believer in having a dedicated workspace and desk, and always doing your work there. It adds a sense of discipline and order to your day. It keeps you focused on your business goals.
My law background has been invaluable in business. But as a lawyer I was always in the position of recommending and advising. I was never the decisionmaker, but I wanted to be! At first I scratched this itch by gradually taking on other opportunities and roles in the company I was in. For the first decade we were pretty much in survival mode. It was feast or famine around here, based on individual ad sales that either happened or didn’t.
