Well if you have a motivation problem... it just seems like you are unsure about what you really want to do in the future. I feel like you will have to crack that first. Figure out and establish some goals, only then you may have motivation to complete whatever assignments or work that get you there. 

This is definitely something I have found helpful for myself, I have had motivation issues in the past and I can pretty much relate to your situation here. 

Besides, I have heard that some people find their motivation from those "motivational" YouTube videos as well, though I have never believed in or seen any... I suppose it's worth a shot?

Even if its a short term goal like treating yourself to something, I think its still going to provide you with some motivation to get off you arse and start working.
