We could make an impression on another person with an impassioned speech, but we are unlikely to change their mind unless we show them that we actually appreciate their position. Not that we validate it, but that we accept it. It is what it is. From there we can begin a journey. The first step is to show the other person how their ideas have influenced us, what we've learned, and how we're going to change based on learning from them.
When I started studying training as a profession, my role models made a point that adult learners are competent. They are NOT looking to be fixed. We should start by asking them how they are currently coping with challenges. What do they know and how have they succeeded? We learn together.

Influence comes through interaction.
