Motivating myself to study?
This (lack of motivation) is common in graduate school.  Without delving into the way you personally like to work (whether you are intrinsically or extrinsically motivated, whether your advisor is involved or uninvolved, whether you are motivated by reward or punishment, etc.), it's difficult to give specific advice.

These are some general motivational strategies:


Get up and start something small.  Doesn't matter what it is.  As long as you are working on your project (even formatting your thesis), you are okay.  This is not to say you should be working on it all the time, just that even the small things are helpful.  Small tasks get you into the groove and ready to tackle larger problems.
Leave things unfinished from the day before.  If you reach the end of the day and are in the middle of a task, leave it, don't stay up to finish it.  This way you have to get up in the morning to keep doing what you were doing, rather than waking up and saying "I don't know where to start."


Finally, if you think you may be depressed (if you are constantly saying "I have no reason to get out of bed"), please talk to someone or see a doctor.  It gets better.
