One time I was in a really run-down thrift store looking for anything neat that stood out. A random guy asked how I was doing and y'know, I tried to be genuine enough, but in return he gave what is now one of my favorite replies:
"Too blessed t'be stressed!"
The delivery of it was like he actually meant it. Like he was just enjoying his day lookin' at stuff and nothing could bother him.
It's a good outlook, y'know... especially because at the time I was in a miserable job and often used the "Been better" and "I'm here." Responses because I just didn't have much else in me.
