Both of my kids are grown and now I have so much free time on my hands, what should I do?

Free time? . U can do what ever u desire, but remember u children no matter how old r they , still in need of u love and attention.
Feeling purposeful. With an "empty nest, " many start to notice more free time. It is important to continue feeling purposeful; initially with raising two children, now with giving back to the community or other volunteer activities. Some ideas include volunteering at a local hospital or nursing home, reading to kids at school or a public library, using your skills at a local non-profit organizations, etc.
