How do I sit with being so good at getting people to say what I want?

You have become powerful at this. You can open almost any witness and steer them toward the words you need, and the very skill has started to unsettle you. That wariness is not a problem to fix. It is your conscience keeping pace with your ability, and that is a rarer and better thing than the skill itself. Power over people is a tool, and tools are judged by their use. Used to draw out the truth a witness is hiding, your skill serves justice. Used to make someone say what is convenient rather than what is true, it corrupts. The uneasiness you feel is the compass telling you to keep asking which one you are doing. Do not silence it. Let that wariness stay close and guide your choices. Before a deposition, ask yourself plainly whether you are after the truth or just a win. Most days the honest answer will keep you clean. The lawyers to fear are the ones who never wonder. You are not one of them, and staying that way is worth more than any technique you have mastered.
