How to find motivation to learn?

I've been in the Q-phase since this year and had actually resolved to finally do something for school this school year and next. The school year has been going on for almost a month now, and so far, nothing has worked out. I have to hand in a three-page thesis paper the day after tomorrow, but I haven't even started yet.

I've also asked my friends and parents for motivational tips, but the answer I always got was that I should relax and that I'm already good enough.

I have to say that in recent years, I've always had an average grade of 1.2-1.4 without having to do anything in the afternoons or on weekends. I only put in the effort for group projects/group presentations because I didn't want to let the others down. But otherwise, I really didn't do anything, not even submitting research papers or creating a PowerPoint presentation for individual presentations.

I don't think my grades so far are bad, but I do know that I have a chance of getting a grade of zero if I work hard, and I don't want to just throw them away. I just want to avoid regretting later on that I didn't do more for school.

So my question to you is: Do you have any tips on what I could do to become more motivated for school?
