Morley is a street artist, similar in that regard to Hanksy, from Los Angeles - where I currently happen to live. If Hanksy is all about the puns, Morley is all about the writing. He is a pretty good one if you ask me.
For the last thirteen or so years of my young life (I'm 30 if anyone's counting) I've been preoccupied with the notion that my value on planet earth was defined by my career (or lack thereof). Similarly that my career defined who I was a person- that when introduced to someone I might as well have said "Hi, my name is Clerk at Blockbuster. It's nice to meet you Genius at Apple Store".
You can read more about the piece at his website. Does your job define you? Does it give you a justified existence? It's a tough question, if you ask me. While work does give many people drive and some sense of purpose, it shouldn't be what you use as justification for your life. But that is if you ask me.
Sidenote: His website is filled with great things like his list of 50 Wonderful Things. The list is populated with things like "when your turn signal rhythm matches with the signal of the car in front of you" and "the rare occasions when Tom & Jerry set aside their differences and team up against a common foe."
