After talking with a few friends and instructors, I've concluded that it's a lack of energy rather than motivation. However, I thank all of you for your responses. What do you guys do to stay "energized" for your training? I currently use flash cards and training videos. Perhaps, I should try to make a group meetup with other students? I do believe my energy levels are affected do to outside stress and factors because I am constantly battling sinuses/allergy issues. Unfortunately, I'm still waiting for medical coverage to get examined by a doctor. Also, my father stated today that I could have hypo thyroid issues because he and my grandma have that problem.

Once again, thank you all for the replies and look forward to hearing more about what you guys do to keep energy high during your flight training.
