Does someone occasionally getting small satisfactions equal them thinking there is meaning in life? If so, we're using very different definitions of meaning. I think people can think there is no meaning and also be capable of occasional positive experiences.

(I don't understand the second quote so can't comment on it.)

One of my favorite poems is Be Drunk[0]. Would you take someone agreeing with the "thesis" of Be Drunk (thinking it's necessary to numb yourself against meaninglessness through diversions like alcohol or poetry) as unable to be a nihilist, because they are capable of distracting themselves from meaninglessness?

ETA: I don't think "is there anything meaningful in your life" uses the word "meaning" in the same was as the question "does life have meaning." Maybe the below commentor was totally correct about us all talking past each other, because the first question seems to ask "does anything reliably bring you joy" while the second asks "is there a purpose to existence." Someone could have things that matter to them while still thinking existence is purposeless.
