Dream Dream Dream

What is the significance of dreams? why does everyone feel the need to have a goal to work to of what they want to do with their life and push it aside saying that's never going to happen- it might if you work hard enough for it! No-one gets what they want just by sitting around and waiting for it- you've got to go out and make it happen. 
My dreams:

• Live in Paris
• Become an english lit teacher.
