Stellium in Capricorn

What does Stellium in Capricorn mean in the natal chart?

Three or more planets in Capricorn make you built to carry weight — responsibility, real craftsmanship, the kind of authority people lean on. You grew up steady, maybe sooner than you should have. The risk is loading so much onto your own shoulders that you forget why you started building in the first place, until rest itself starts to feel like cheating. It isn't. You're allowed to set the stones down.
