nOne sort of resolution has to do only with oneself. You might decide to stop eating candy, to exercise more, or to watch less TV.
nOther resolutions might involve family or friends. You could resolve to be more patient with your little brother, to be more helpful to your mom, or not to get into fights with your friends.
nSome resolutions are about school and the outside world, such as getting to class on time, trying for better grades, or not teasing the neighbor's dog.
