And not only will you make everyone's lives better - seemingly ironically, by simply accepting the fact that you're often wrong, you actually make it more likely that you'll be right.
That's the part that I think people especially need to understand, since a refusal to admit that you're wrong is generally rooted in an ego-driven need to be right, and refusing to admit that you're wrong guarantees that right is the one thing that you won't be. You'll just keep clinging to the same wrong idea and keep failing to fulfill that need to be right.
If, on the other hand, you just freely admit that you're wrong, then you're instantly free to move on to another, and better, position, making it that much more likely that you'll actually be right. And if you don't get it that time, that's fine - just freely admit that you're wrong again and move on again. Keep doing that and sooner or later you actually will be right, instead of just pretending to be.
So you'll not only make everyone's lives more pleasant - you'll actually better serve your desire to be right. What more could you want?
