Am I Right for This Program

First, let me say that I am thrilled to have been accepted by the Group. I have devoured the first 2 books and am almost halfway through the third. I seem to be learning so much but what worries me is this. I am a 74yr old retiree. Can I accomplish anything worthwhile if I am not in the workforce any longer? I want so to make the remainder of my life and that of my husbands meaningful. We, like many seniors, have fallen into the retirement rut. We only make it month to month with a little left over for wiggle room…not enough for the traveling we had hoped for prior to retirement.
