Let's take the example of a kid who wants to become an astronaut. She requires to see how what she does now will affect her future, and how she can work to realize that dream.
You could decorate a wall mural to assist her visualize the process. Paint the wall to look like a beautiful space-scape, with the Milky Way as a path she walks on to reach her prize.  Paint a space shuttle and astronaut space walking beside it, as the prize at the end of the Milky Way path. 

Then, along the Milky Way path, stagger a few small cork boards covered in black felt. On each one, put a representation of some thing she must do to reach her goal. In this case, that could be excelling in math, becoming healthy and strong, and developing good communication and interpersonal skills.  On one felt covered cork board, hang photos of organic vegetables and good sources of protein. Include diagrams of exercises she should do to build muscle and increase flexibility. Be sure to add a cartoon of her sleeping soundly, as that's an crucial part of staying healthy. If she's as well young to do serious exercises, then have a photo of her brushing her teeth. On the next felt covered cork board, hang the multiplication tables, or what ever her next challenge is to learn in her math class.
