Ben Bradbury is a large advocate for surrounding oneself with disagreement.
"The people that you surround yourself with are there to push you forward, but they are also there to call you out. Yes, you want to surround yourself with people who are aligned with your why and people who will keep your why burning. Motivation is a little bit like taking a shower. You need it once a day. Also, you need people who know when you are going too far in the wrong direction. Be glass half full with building communities and surrounding yourself with the right mission, but also be ruthless with yourself. You are flawed and you will make mistakes. So, you will need people who will cut your rate of mistakes as quickly as possible. So, go out there and find that balance".
You do not want people who echo your thought because, then, what progress has been made? Sometimes you need people to call you out in order to get you back on the correct path.
