It's a really tough lesson to learn but this is absolutely true: It is not enough to be right, you must also have credibility. You usually have to accept other people being wrong about things you're right about in order to build credibility.

I don’t think this is the correct way to look at it. Rather than accepting other people being wrong, you should be very open to the possibility that it’s you who is wrong. Always doubt your own assumptions, and be willing to change your stance when new information comes to light.

I think my quote would be better if it said "often" or "sometimes" instead of "usually". But no, I disagree with your point here, I mean, that's true too, but it's not what I was talking about. I'm saying that in order to build up a lot of credibility, you have to be right, tell people the right thing, but actually not fight them when they disagree and go a different way. If you were actually right and they were actually wrong, they will know and remember and trust you more in the future. Doing variations of this for a long time in view of a lot of people is one of the places credibility comes from. But you actually do need to pick fewer battles and let more wrong decisions go, even when you are actually right. That's part of the lesson that has to be learned when you don't have the power. It isn't enough to be right, you have to be trusted by the people who make decisions, and for that you have to build credibility.

I think you absolutely need to be open to being wrong about things.

But that's independent to building enough credibility to be able to speak truth to power.
