The best advice I ever received as a young man (apart from my dad's): Never be afraid to change your mind.
Rereading C.S. Lewis's The Last Battle as a middle-aged man has had a much different effect on me than it did as a child. The Dwarfs' cry, 'The Dwarfs are for the Dwarfs!' used to feel like loyalty. Now it reads like a warning.
The Dwarfs become so entrenched in their position that they can't see anything else. They've built walls so high around their beliefs that even when rescue arrives, they mistake it for another trap.
Sound familiar?
Social media has turned us all into potential Dwarfs. We curate our feeds, choose our tribes, and reinforce our existing views until changing our minds feels like betrayal rather than growth. Potential truths are decried as conspiracy. The algorithm rewards certainty, not curiosity.
Your mind isn't a fortress to be defended. It's a workshop where ideas get tested, improved, or scrapped entirely. And trust me, I've scrapped some truly silly ones over the years.
What belief are you holding on to simply because you've held it for so long?
