Dreams and Reality

Time spent wishing is time wasted. True or false?
I was watching Scrubs (ironic series about young doctors) old seasons and there was this quote about wishes. So, really? So now I must stop dreaming and wishing? On the other hand you can dream but you have to do something to make that dream come true. Without actions it is pointless to dream or wish, I guess.
I hate to see reality, isn't it better to live without actually seeing what's going on with the world? I almost stopped reading newspapers, cause everytime I try to do that, there are always sad stories, cruel stories, somebody was killed, something stolen, articles about economy collapsing and members of parlament expressing their opinion on the things they actually know nothing and so on and so on. I am tired. How about that recent event in Finland where boy killed his classmates (I didn't managed to read whole story)? How about that writers strike in LA? I was always sceptic about people saying that their life dream/aim/wish is the peace in the world. Well, now I really want this to happen, I want everyone live in peace with each other, no more iraqs, no more cold wars, no more starving people or battered wives and children. Please stop everyting. And that's not because I am very good, kind person, it's because I want to live between good people, stop worrying about others' problems and start taking care of my own.
Ok, no more existential talk. Have a good weekend.
