"The problem with making assumptions is that we believe they are the truth. We could swear they are real. We make assumptions about what others are doing or thinking — we take it personally — then we blame them and react by sending emotional poison with our word. That is why whenever we make assumptions, we’re asking for problems. We make an assumption, we misunderstand, we take it personally, and we end up creating a whole big drama for nothing."

- Miguel Ruiz, The Four Agreements
