What a week this has been! You might recall that on Monday, I posted an essay called “To Marci, On Your 20th Birthday,” which I wrote as part of a “blog hop” sponsored by Generation Fabulous, an amazing Facebook group to which I’m honored to belong. (We lovingly call it GenFab.) If you haven’t had a chance to read that post yet, please do, and please check out the posts by my GenFab compatriots. There’s a lot of collected wisdom there, and it seems that the Huffington Post agrees. Three Huffington Post sections—HuffPost Women, HuffPost50, and HuffPost Healthy Living—as well as HuffPostLiving’s Facebook page, featured 14 of us in an article about our blog hop. (You can find my quote on the second panel of the Huffington Post slideshow.)

My deepest thanks to the GenFab troika: Chloe Jeffreys of “The Chloe Chronicles,” Sharon Greenthal, who writes “Empty Nest, Full Mind,” and Anne Parris, the voice behind “Not A Supermom.”

The question—”What Advice Would You Give Your 20-Year-old Self?”—is really striking a chord with readers: people all over are sharing and commenting. I’d love to give readers of “The Midlife Second Wife” a chance to weigh in on the topic. So tell me:

What would you say to your 20-year-old self?
