Without knowing you, it is difficult to make any sensible suggestions. Positive character means things you do that are for the good of other people or situations, and not done for personal gain or glory. So -- what do you do that fits that parameter? Do you do any volunteer work, in school or out of school? Are you involved in a youth organization such as Scouts, 4H or whatever? Often there are leadership roles within these organization that are filled by the members. And most have community help goals as well.
Are you a cheerful person to be around? Are you positive in your outlook? Do you help other people willingly - even when you aren't asked? These are all aspects of positive character, along with such things as truthfulness, honesty, etc.
You are the only one who can evaluate these, so sit down and do some contemplative thinking.
Good luck with your essay.
PS - this is a difficult assignment, as listing the good things about yourself sounds like bragging, and most people don't like to do that. But since your assignment is specifically asking for the good things about you, you can list them with aplomb and not feel embarrassed.
