I think it's so wonderfully and beautifully put, but can't find the source, and am curious as to whether or not it's a genuine quotation.
The quote is not Camus'. But, apparently, misquoting Camus, or even fabricating quotes is something of an enterprise. Gaetani even has papaer on it The noble art of misquoting Camus. They include "I would rather live my life as if there is a God, and die to find out there isn't, than live my life as if there isn't, and die to find out there is", "Don't walk behind me; I may not lead. Don't walk in front of me; I may not follow. Just walk beside me and be my friend"; "Life is a sum of all your choices. So, what are you doing today?", "By your actions or your silence, you, too, enter the fray", and so on. Perhaps his style invites imitation.
This one comes from a fake letter of unclear origins, ironically signed "falsely yours":
"My dear, I don’t know what to do today, help me decide. Should I cut myself open and pour my heart on these pages? Or should I sit here and do nothing, nobody’s asking anything of me after all. Should I jump off the cliff that has my heart beating so and develop my wings on the way down? Or should I step back from the edge, and let the others deal with this thing called courage. Should I stare back at the existential abyss that haunts me so and try desperately to grab from it a sense of self? Or should I keep walking half-asleep, only half-looking at it every now and then in times in which I can’t help doing anything but? Should I kill myself or have a cup of coffee? Falsely yours, Albert Camus’."
The quote spread over the internet from The Paradox of Choice by an American psychologist Barry Schwartz, and Al Gini's Why It's Hard To Be Good. Neither names any sources. A poster on fuckyeahcamus blog, who did extensive searches on it, including The Stranger, where it also is not, muses "As we know and is exemplified through the proliferation of quotes misattributed to minds like Gandhi or Einstein (“If you judge a fish by its ability to climb a tree…”), the Internet loves to put words into the mouths of well-known intellectuals."
Sorry for the late answer
Indeed this quote does originate from Camus. In the first section of “A Happy Death”, the character Mersault stated this in conversation with the character of Zagreus, following with a consideration that it takes extraordinary courage to remain amongst the living as opposed to succumb to death.
"Should I kill myself, or have a cup of coffee? But in the end one needs more courage to live than to kill himself."
-Camus, in A Happy Death
See discussion of his point here: was Camus right in saying 'There is but one truly serious philosophical problem and that is suicide.'?
“Sometimes there are days when you’d like to change places with him. But sometimes it takes more courage to live than to shoot yourself“. That is the actual quote by Mersault after he kills Zagreus. (From A Happy Death) The bastardization of the quote to add the coffee part is disappointing. Camus doesn’t need to be altered to be brilliant and applicable.
