Motivation

I have several students that are extremely smart, but they are not motivated to learn or even try to learn. They do not really see themselves being successful or continueing their education, so they do not want to put forth any effort. I try to motivate them, but it seems they would rather put their effort into getting into trouble rather than their work. It doesn't matter what rewards they get, it just is not enough. I want them to be successful and I am trying to build their confidence for their future.
