However many bizarre, otherworldly rules your workplace may come up with; however many asinine customers you may have to handle that day... remember the following.
Your job is not who you are. Your job cannot define who you are, unless you allow it to. Your job can move the goalposts every day, but they cannot make you give a damn. They can make time appear to pass more slowly, but they cannot stop the clock moving.
Keep smiling, pay token homage to their rules, and remember they can do you no lasting harm.
