Niceties & Pleasantries Not Required

When you know what you are doing, give yourself the chance to do what you oughta do. Not everybody has to understand it and accept it - or even follow along. You don’t need permission from others for every single step you take. You may have the option to report back and let them chime in, and that can go in your favor, but keep it from detracting from your work. Furthermore, you can minimize distractions (including socialization). Being "rude" in that sense won’t matter at all when results (and simply moving toward them) make up for it.
