The number one thing impeding people from their own growth and development is their assumption that they know everything already (which is why they often listen to just affirm their own beliefs).
This in turn relates to a question I had a very long time ago about trying to help people in corporate environments but without much success. “How can you help someone who doesn’t want your help?”
The reason you can’t help them and they don’t want your help is because they think they know everything and have it all figured out already. In other words, they don’t realize that their own belief that they have everything figured out is in itself a misperception that is causing them suffering.
It’s only when someone goes through that repeated suffering and finally realizes they haven’t got everything figured out and actually asks for help…or at the very least steps back from their beliefs and begin to question them…that they can begin to grow and develop again.
That said though, I think our world is going to go through a whole lot more suffering before people begin to wake up and realize that they’re belief that they have everything figured out is the main reason why their world(view) is collapsing in the first place.
