A good time to take your blood pressure -- if it's not elevated now, you're in really good shape. It can be easy to get worried about health matters now, but moderation is the right response. The temptation to throw yourself into a new regimen may run high, but choose your new path well before you embark or it will be a flash in the pan. The same goes for cleaning house in the workplace and starting off on a fresh footing. Make sure you're not demanding too much of yourself in the long run -- you will not always have this much drive, and you don't want to peter out because you can't keep up with yourself. A good program is determined by whether you can keep it going on an off day.
