You are always acting as a fortune-teller in your own life by the way you think and kotalk about how situations are going to turn out. When you confidentially expect good things to happen, good things usually happen to you. If you expect negative things to happen you are usually not disappointed.

The Law of Expectations

Your expectations have inordinate effect on the people around you as well. What you expect from people around you as well. What you expect from people and situations determines your attitude toward them more than any other factor, and the people reflect your attitude right back at you, like a mirror, whether positive or negative.

Dr Robert Rosenthal of Harvard conducted dozens of controlled experiments over the years to test the power of the expectations of teachers on student performance. In his landmark book, Pygmalion in the Classroom, he tells of case after case where teachers were told that a student, or sometimes a whole class, was extremely bright and was predicted to make a quantum leap in academic performance in the coming year.

Even though the students were chosen from the school population at large,as long as the teacher believed that the students were exceptional, and the teacher expected the students to do well, the students performed vastly better than the other students in the same or similar classes, and vastly better than could have been predicted by previous grades or behavior.
