The Mercury in Libra Pattern
You shape your words to please your audience. Not because you're dishonest — because you genuinely see every perspective and want to honor all of them. But the cost is that nobody knows what YOU actually think. You agree with the conservative and the progressive. You validate the plaintiff and the defendant. You nod at contradictory opinions in the same conversation. Your growth comes from staking a claim — saying 'I believe this' without qualifying it with 'but I can see why someone might think...'
