Changing people’s word view is hard. Yes, most people can change. But they’ll only change for a select few.
I could tell a million people to stop eating sugar. But unless they hear it from their spouse, they’re not changing.
So, you wanna change people’s world view?
Preach to the ones who already share your perspective. Spouses, in this example.
Then, and only then, can you change people’s world view.
