Break down your study goals into smaller, more attainable chunks. Instead of panicking over the final page count for a long essay, take on each subtopic in the essay individually, and overcome them one by one.
Another way to stay motivated to complete your homework is to tie a carrot to the end of the stick, so to speak. For example, you can tell yourself, “Once I finish this assignment, and only when I’ve finished this assignment, I can hang out with my friends or play video games.”
Of course, you can also motivate yourself to complete your homework by thinking about how your accomplishment will positively benefit your future. You can think along the lines of, “If I stop procrastinating on this homework assignment and finish it now, I’ll get a better grade in class. If I get a better grade in class, my overall GPA will be higher, and I will look better on my college applications!”
