Secure people can change their minds without feeling smaller.

Changing your mind only feels like a loss if you have staked your worth on the position. When you have not, a revision is just an update, and you can make it out loud without flinching. This is why secure people can be talked out of things and insecure people cannot.

Practice saying that you have changed your view on something small and low-stakes. Notice that nothing bad happens. Building that tolerance makes the important revisions possible later.
