The Mercury in Leo Pattern
You communicate for impact. Every story has a punchline, every opinion has conviction, every conversation has a moment where you shine. Your mind organizes thoughts into performances — and the audience's reaction tells you whether the performance was good enough. But when no one claps, when your brilliant observation lands flat, it doesn't just feel like a bad joke. It feels like you don't matter. Your growth comes from speaking simply, without performance, and discovering that your thoughts have value even without applause.

You're the friend who makes every group text entertaining, who gives the toast at the party, and who tells stories that captivate the whole table.
