There's a massive difference between knowing you're loved and actually feeling loved. Dr. Algoe's research found that appreciation doesn't just feel good, it transforms relationships by triggering oxytocin, the bonding hormone. Expressing love literally reduces your own stress hormones and blood pressure. Billy shares how growing up in chaos taught him to never hold back those words, and how saying "I love you" amidst brokenness with his siblings brings healing that time alone never could. Pick one person today and tell them exactly why they matter. Text it, say it, write it on a sticky note. Just get it out of your head and into their heart.
