Being over 50, Robert Bly's new book Start Your Own Home Business After 50 caught my eye.
I read the introduction and skimmed the ideas he wrote up for home businesses well suited to mature adults.
Robert Bly gives the outline of the plan, an action plan for acquiring whatever you need to start, how to market effectively, and some possible drawbacks. All in all, he gives you enough information to make an informed decision. Most of the businesses can be started with a small investment.
Maybe you will find a way to work from home full-time or part-time to enhance your retirement options.
