Taking no sh*t doesn't mean being rude or unkind. It merely means to not let anyone stop you from achieving your dreams or living your life. However, that's not all there is to it.
"Do no harm, but take no sh*t."
The other half of taking no sh*t is doing no harm. You see, karma is a very real thing. If you treat people poorly, you'll get treated poorly. Treat the world the way you want to be treated, and you won't have to worry about it treating you badly.
Big Dude, you were king at this. I just hope I can be as good at it as you were.
Love, Bubba
