Many scholarships require you to write an essay. Be sure to do your best on the essay, because for many scholarships, the quality of the essay makes a difference as to who receives the scholarships. Stay away from general ideas, such as saying that you are interested in a particular program because you think it will help you to "grow as a person" and "be more open to other cultures". Think specifically about how a particular experience may help your career and personal goals in the particular country that you are going to.
Do take the time to apply for scholarships. Every year there are scholarships that remained unclaimed because not enough students applied. Even if you do not meet the criteria exactly, you may be the closest to it of all the people who have applied.
