We knew Miley Cyrus was thoughtful for her age (girl has been known to tweet some insightful, Oprah-like ish), but hearing her talk about the advice she would share with her younger self basically proves that Miley's puppy-loving heart is incredibly wise! And it seems like she's acquired such wisdom through painful young heartbreak.

During an upcoming interview on our new favorite show, "The Conversation with Amanda De Cadenet," Miley's asked what she would tell her 14-year-old self now that she's grown-and-sexy. (If you don't know the show's premise, basically celebs sit with the host on a cozy couch and dish their deepest, darkest secrets. AKA our dream job.) "This too shall pass... that's something I so needed to remember," Miley replies. She then goes on to reflect about her biggest heartbreak, which happened when she was 14 (OMG, is she talking about her split with Nick Jonas?), and how it devastated her: "I was so in love with somebody... [I thought] the rest of my life was ruined because he didn't love me..." No worries -- Miley confesses that she's moved on, and we entirely believe her. Her current boyfriend is Liam Hemsworth, so we think she's healed just fine.

+ Watch a sneak peek of Miley Cyrus on "The Conversation" after the jump. Her episode airs tonight on Lifetime at 11 p.m. ET.
