Being retired is not the time to take the time to learn about finance. Younger people need to take the time now to learn. In twenty years what is going to be the best time spent, 20 hours a week watching football or movies, or 20 hours a week learning about all the new ways and means to earn extra money. Is self education of a game more important than self education of learning the ins and outs of savings and compound interest.

Do not wait until you are retired. Start learning now.
