Mine are attitudinal. For me they definitely relate to low-carbing as a WOE/L.

"Unthinking respect for authority is the greatest enemy of truth." (Albert Einstein)

"A pessimist sees the difficulty in every opportunity; an optimist sees the opportunity in every difficulty." (Sir Winston Churchill)

"A realist sees things for what they are, a cynic sees things for what they are not." (Me)

And my favorite is from Robert A. Heinlein's "The Moon is a Harsh Mistress"

"A rational anarchist believes that ... it is impossible to shift blame, share blame, distribute blame. . . as blame, guilt, responsibility are matters taking place inside human beings singly and nowhere else. But being rational, [s]he knows that not all individuals hold [her]his evaluations, so [s]he tries to live perfectly in an imperfect world. . . aware that [her]his effort will be less than perfect yet undismayed by self-knowledge of self-failure."
