A pile of bricks

It’s difficult for a person to change the way he sees things. The more he sees things in a certain way, the more things appear to be the way he sees them. So, when a person gets set in his thinking it’s hard to change that thinking. The more the person has been thinking the thoughts he’s been thinking, the more difficult it is. One thought sits on top of another and another on top of that. As the days pass by they all pile up one on top of another. Like a pile of bricks. Even with a hammer it’s difficult to knock it down.
