One of the best definitions of an anarchist comes from Ursula K Le Guin:
"One who, choosing, accepts the responsibility of choice."
When was the last time you chose, regardless of the propaganda of the state or any other hierarchy, to ignore a stupid rule and accepted the responsibility for your choice? That's when you were an anarchist, whether you knew it or not. The more often you do it, the more of an anarchist you become.
Another comes from Robert Heinlein:
"I am free, no matter what rules surround me. If I find them tolerable, I tolerate them; if I find them too obnoxious, I break them. I am free because I know that I alone am morally responsible for everything I do"
If you have a heart and mind that long for freedom, you are an anarchist.
