The world of internet has already shown you many expectation vs reality pictures. By now you might have understood, how the situations that you dream could change in real-world. But still many of us love day-dreaming about things by giving a large and beautiful expectation.
The real problem with such expectations is that, once you taste the bitter side of reality, then all your confidence will be lost and you’ll finally end up in a real bad depression. The more you expect about the outcome, the more are the chances of losing hope in yourself. You can never change the worst realities that you’ll get as a result of your high expectations.
