When I'm at work, I never seem to find the time to stop and recharge my batteries, even for a few minutes. I seem to be on the go from the minute I arrive until the moment I leave. On the train journey home, however, I join the army of passengers using laptop computers, because it means I can catch up on my emails.
It allows me to deal with all my communications before I arrive home. That way, when I step through my front door, I have time to enjoy some quality time with my wife and children.
