You run on being fully, visibly yourself. Not attention for its own sake — coherence. What you feel, say, and do line up in public, and that alignment reads as warmth with a spine. People borrow confidence from you and rarely notice they're doing it.
The cost is the dimmer switch you don't have. On the days you can't shine, you'd rather not show up at all, and being overlooked doesn't just sting — it disorients, like the room stopped making sense.
The Sun doesn't audition; it rises. The practice is letting yourself be ordinary in company and noticing that nobody leaves. The warmth was never conditional on the performance. It's just you, and it was always enough.
