Control WHEN an event happens. Be calm, not reactive, move more slowly and confidently than the counterpart.
WHO matters more? What do they want? What is my unique offering that addresses that? Make myself valuable to them. Make myself seem like the important one. I screen others to work with me, I don't come needy. Believe that I have power, that I don't need any specific person.
Control WHERE an interaction happens. Break the social rituals (such as being on opposite sides of a table) that create uneven power dynamics, without making a big deal of it.
Control WHAT I focus on. In a conversation, I should be saying the things that it benefits me to say, and avoid getting pulled into someone else's narrative or tricks.
