What should I do with my nostrils? Can I make it smaller without inserting any kinds of implant? (photos)

i want to do something with my nostrils. Even though most people think that there is nothing wrong with them, and i kind of think so too. But i think it would be nice to make them smaller. I want to know if it would be possible for me to get smaller nostrils without inserting any kinds of implants (including those ear cartilage implants). I want to make my nostrils smaller and slimmer, is it possible to reduce the size of the nostrils without having any kinds of implants inserted to the nose?
