Don't focus on the negative and/or negative self-talk (i.e. "I can't do this") or try to get yourself motivated by fear (ie. "if I flunk out then xxxxx")
You need to find out the positive motivation that your shooting for (good job, particular lifestyle, etc) and drive TOWARDS that, not AWAY from anything. Love is infinately more powerful in the long term (and more rewarding) than fear.
Somehow hook your schooling to something else you love.
