Investing: It's All About Making Your Money Work

[摘要] Daniel Chaffin, M.D., says he has never been at the top of the physician pay charts. That's why the solo practitioner in San Rafael, Calif., decided long ago to pay close attention to his finances. He dutifully put money in a retirement plan each year, avoided speculations, and focused his attention on growth-oriented stocks and stock mutual funds. The result: A seven-digit retirement account, additional investments on the side and, in short, financial security for himself and his wife as he nears his 70th birthday.
