Don't be so attatched to your opinions, and be more open to hearing other people out. Emotional connection to your beliefs is hinders growth because it more often than not blocks you from exploring the possibility that you are wrong.
For superforecasters, beliefs are hypotheses to be tested, not treasures to be guarded. It would be facile to reduce superforecasting to a bumper-sticker slogan, but if I had to, that would be it.

There is a section where they describe this like a Jenga, and the beliefs that we connect strongly to our identity are located on the bottom and are thus harder to remove.
Commitment can come in many forms, but a useful way to think of it is to visualize the children’s game Jenga, which starts with building blocks stacked one on top of another to form a little tower. Players take turns removing building blocks until someone removes the block that topples the tower. Our beliefs about ourselves and the world are built on each other in a Jenga-like fashion. My belief that Keynes said “When the facts change, I change my mind” was a block sitting at the apex. It supported nothing else, so I could easily pick it up and toss it without disturbing other blocks. But when Jean-Pierre makes a forecast in his specialty, that block is lower in the structure, sitting next to a block of self-perception, near the tower’s core. So it’s a lot harder to pull that block out without upsetting other blocks—which makes Jean-Pierre reluctant to tamper with it.

I can really relate to this and is something I'd personally like to work on.
