one practical note -- i think it's really helpful to have specific goals, and tangible proof of accomplishments -- if you wake up and say "i'm going to study the lsat all day" and prop open a book, and say to yourself at the end of the day that hopefully you got better because you put in X number of hours, you are far less likely to be successful than you would be if you can say "okay, today my goal is X (something specific, like mastering conditional logic for example, or firming up your habits for a specific LR question type)," and then you present yourself with work that validates what you are doing (for example, you do a drill on conditional logic at beginning and end of your studies to see how much you've improved).
I think that improving is addictive. You see it in the folks who start to get the ball rolling downhill, and start figuring out exactly how to get better -- they start seeing more and more tangible proof of improvement, and they want to work more and more -- obviously this is all easier said than done, but see if setting small, specific goals, and having specific ways to gauge improvement, helps you feel a bit more in control and helps you get the sense that you are moving forward --
now, some motivational videos -- not sure what floats your boat, so here's a variety --
