Here are three keys to being more persuasive:
1.Make sure they know you respect their intelligence
2.Make sure they know you respect their character/intentions
3.Make sure they know that you're open to being wrong
These three things will instantly make you 1000x more persuasive with anybody.
*Edit: I realize in many cases you don't respect their intelligence or character, and you're 100% sure you're right, but that doesn't matter. If you want them to listen, you have to disarm their ego and you have to make them think you are open to being wrong. This accomplishes that. So bite the bullet and fake it. You won't be sorry.
Yup, I’ve had a blow up with the high school text group this weekend and the underlying issue with some of them is that I think they already agree with most of my opinions but are too afraid to admit it because they fret over their blue state social status
