This describes me well. How can you find the inner home? How can you be more conscious during conversations? I often come from an interaction with someone thinking: "God, I talked way too much. Should've listened more."
I can't give much advice there, other than be conscious/mindful and practice. Learn to pause between sentences, breathe, ask questions, listen, don't move to a next subject, etc. I think a lot of people have a fear that their soap box will be taken away if they don't fill the space, which... unfortunately isn't wrong because others love to hear themselves talk too.
You might have heard it from other places but meditation. It's literally training you to be present with your thoughts and knowing what exactly is happening in your mind at the moment (and letting it go).
Once you start meditating regularly you can observe that you got tangled up in thoughts quite early on and pull yourself back.
As many practitioners say it helps to create space between impulse and action.
But yeah, it takes conscious effort and practice.
