Fucking Expectations

Following thought has been catching my attention for past couple of weeks:
Whatever happens, one must not loose focus ...

Why do humans expect from their relations? I think because everyone needs support and needs to depend on someone for various needs (emotional, financial, entertainment, intellectual etc.) But, in some situations our own fairly reasonable expectations come back and hurt us. What is the right thing to do then? Should one just cut them down? Or should one just continue and be ready for the possible outcomes? I guess expectations in relations are the reason why society stays interconnected and I believe if they don't exist then the society would be very secluded and aloof as nobody will need nobody and mind their own business. People who practice to expect the least out of their relations are happier or look happier at least??? But honestly, how one can do that? It is so difficult to practice. My viewpoint is that we tend to expect most out of the people we love/care about, or the ones who matters to us the most. Or may be there something else? May be its just psychological, may be we just want to depend? My be we can be fine without any dependence too, but its just becomes a psychological habit to expect and depend?

So, I feel that the most important, real, honest things are the dreams one has and he/she should depend only on them. Nothing else is significant ... hence whatever happens, one must not loose focus on his/her dreams
