In our early/mid-40s, we’re still those college girls at heart, just with more wisdom (and better boundaries).

In this honest, funny, and heartfelt half hour, we write to our younger selves: what we nailed, what we learned the hard way, and the advice we’d whisper to that wild party-school undergrad.

If you’re in your 20s or 30s, consider this your cheat sheet; if you’re any age, you’ll laugh, nod, and maybe grab a pen to write your own “Dear Me.” Don’t miss it.
