Goals are for realists, but dreams are for optimists.

Some people are optimists. Some people are pessimists. I'm just a realist who believes that some things are worth fighting for.

Optimist: day dreamer more elegantly spelled.

A dreamer is a realist with faith.

Lately, a study has suggested that depressed people have a more accurate view of reality, though this accuracy is not worth a bean because it is depressing, and depressed people live shorter lives. Optimists and believers are happier and healthier in their unreal worlds.

It's not the size of the dreamer, it's the size of the dream.
