After a long day of caring about your hygiene, job, and social media presence, you may find yourself identifying with other people who just don't care. By no means should anyone ever begrudge you for not giving a f*ck about how you present yourself in public. Just because you're at a work doesn't mean you need to interrupt your online gambling streak. If other travelers in the airport complain about your pace on the moving walkway, remind them your pace is the only one that matters.
So long as you're not affecting anyone else's tasks or safety, who really cares? Photos of people who are over it might just help you change your second-guessing self into full-fledged no-f*cks-given master. As many older folks would show you, caring about other peoples' opinions is for those who are boring and ugly and serious.
