I volunteer at a car club and part of my role is working with sponsors.
What I've learned i that when you're talking to successful people, price is never the real objection. Value is. If the value is clear, the conversation is easy. If it's not, no price will fix that.
I had to earn those sponsors. I had no authority over them, no leverage. Just a clear case for why working together was worth their time and money. Some of them now come back and bring prizes for our events.
That's influence. Not a title, not authority. Just making the value obvious.
What's a situation where you had to influence someone who had no reason to listen to you?
