People follow consistency longer than charisma.

Charisma is a strong first impression and a weak second year. People stay with someone whose behaviour they can predict, because predictability is what makes it safe to rely on them. Reliability compounds where charm depletes, and everyone eventually learns which one they are dealing with.

Rather than working on presence, work on whether your behaviour matches across weeks. Do you follow through, do you react the same way to the same thing. That consistency is quiet and it is what people actually follow.
