Everyone has their own model of realty. It consists of their ideas and expectations.
This model is always different from reality.
The closer your model gets to reality, the closer your results will be to your expectations.
Some people think they know everything.
They won’t listen to anyone else’s ideas.
They end up frustrated because they don’t get the results they want.
Diversity of ideas is a good thing. Someone else’s idea may be more realistic than your own.
Don’t try to fit in with the crowd. The crowd is usually wrong.
When no one is willing to say so, that’s not good for anyone.
