your sentence, beachbreak is littered with fragments. I don't know how you assess your comment because I don't understand. But my educated guess, no don't quit your job and live on the beach, it doesn't work out on the long run
I guess everybody's definition is different. To me, a few examples would be, people like Jesse or Bethany. Those two are HARD F'N CORE. Or any person who fights and survives for years in hellhole places like Iraq or Afgahinstan....imagine being a surfer fighting in the desert.....thats pretty f'n hardcore.
