You should hold on to your dreams.

Picture from: gettyimages.com

You should hold on to your dreams; if you work hard enough, they'll come true.

This picture is of a man walking down a deserted road. The road represents the long way to get to your dreams. It's a long winding road, often lonely, and deserted. The point is, you have to continue to walk down that road and follow it no matter where it takes you. If you are eating, sleeping and dreaming with that one thing on your mind, you could possibly get there.

I think this also goes along with A Raisin in the Sun, because Walter is forever chasing his dreams. If he would've continued that walk without making stupid mistakes, and decisions, he might have made it, and done what he wanted to with his life.
