One of the most important aspects is proper finger nail maintenance. Let's face it, smoking causes boogers and you need to have properly trimmed nails to really get in there and dig deep without cutting the inner membrane. Since I came in 3rd in the Illinois Deep Dig Nose Picking championship a few years ago, nail maintenance is naturally a part of my routine. Working on your finger dexterity can really help too, especially if you want to go in up to the knuckle. Oh yeah, and wash your hands. We don't want people to think we're boogery savages.
