Great Expectations

The wonderful novel by Charles Dickens, and one of my favorites, although I never knew who exactly had these expectations. In the novel, it has mentioned that Pip had great expectations; in my opinion they all had their expectations. But yes may be the greatest expectations belonged to Pip. The reason was that his expectation was to be up to Estella's expectations. So in comparison he had the greatest expectations.
Some people including myself fell in the trap of trying and working to be up to someone else's expectations, some other people exert great effort to be up to everyone's expectations. but usually it ends up in disappointment.
So is it something that can be practiced? I wonder if I have zero expectations how life would look like. Well, it has its pros and cons, but there will surely be a lot of surprises.
Oddly enough we normally don't know what do others expect. And they don't know what are our expectations too… so we are all left with some possibilities and assumptions. And the ones who care will always torture themselves that may be what they did wasn't enough.
There is only one way to know anyways, try !. I am beginning to think, the more positive way is to work not expect. I am not comfortable at my current job so I would better look for another, I don't want to expect someone's call turn the phone off. I am becoming less patient, but may be I need to be less patient, I have waited long enough and why don't I be more impulsive… don't really know.
