Renee Bergeron, Vice President, Managed Services, Cloud Computing, Ingram Micro:
I try to keep the two separate: when I work, I work and when I am not working, I am not working. It's too easy to check the BlackBerry on the weekend, so instead I give myself 60 or 120 minutes to catch up with work over the weekend and am very productive because I do it in a concentrated fashion, instead of ongoing. Being able to focus on my personal life helps a great deal to reduce stress and actually makes it easier to focus on my work during work hours. I run on a regular basis, which helps too.
