I may not have to take "classes" in the university sense anymore, but I sure have to keep up with professional education. As a CPA I need 80 hours every 2 years to keep my license to practice valid. Granted, not much compared to a full course load, but it never stops. Living in the rainy northwest, I have a lot of time in the winter to do the hours. An accounting professional organization offers unlimited online education for about $150 a year. Now THAT'S A BARGAIN!
