We get what we diserve, do we?

Here there is something that is bothering me for the past week. We meet people, we always think ahead. I guess this is human nature. And, sometime, our thoughts are right...but, once in a while, we do the worse mistake you can imagine. Here it is my idea, the only solution to this behavior is stop thinking ahead, stop trying to predict what is going to happen or stop thinking what other people are thinking. That will solve the problem: "Expectations". Why do we have to expect? Why can't we just live our lives without expectations? Our lives will be easier and simpler. we will be like robots or computers. But then, our live will not be excited. Do we need excitement? Do we get excited with expectations? Anyways, I am not going to change. I don't want to change. I will keep expecting and I will keep being excited with expectations. Please, God help me.
