I see your point of view and understand it. You count in hope. You hope that things will work out well everyday, without being certain; you have faith in life and I respect that.
But, the truth is that life is bittersweet - more bitter than sweet, actually - and hope alone is not always enough. We can still hope, but if our hopes/ dreams never come true, then it is only logical that we stop dreaming/ hoping. And that's were the cynical part of our life begins.
I'm not saying that I'm happy about that. I would like to hope and dream as well, but I know that what I hope for, what I dream for, is just not going to happen.
So I give up. I gave up some time ago. And I think that (unfortunately) many people have given up as well.

Just my humble thoughts.
