Take nothing for granted. Organizations have short memories and you can be out of a job in a flash. Keep your options open by having other work to fall back on. Never assume that the organization is as loyal as you are. If you anticipate a management preference for youth, consider moonlighting or developing a new career path.
Career changes can be one of the most energizing aspects of aging.
A study of retired professionals I conducted several years ago in the Palm Springs, Calif., area suggests that most of them find retirement boring without work. Many have developed new career paths and say their new work is more exciting. Keep your eyes and ears open for signs of change, however subtle. Be sure to see who's the rising star in the company and protect your turf. Don't let anyone invade your turf without resisting.
