The fact that life has no inherent meaning has no bearing on whether or not my life has meaning as meaning is something that (in a meaningless universe) must be entirely subjective and individualized

While life may be meaningless in the grand scheme of things, this does not exclude the possibility of meaning within your life. The question is not whether or not there is meaning in your life but more is the meaning that you assign to your life real. Personally i believe that while my life may be worthless in the grand scheme of things it is most definitely meaningful to me for if it wasn't then i would have no reason to not kill myself. By using this logic i am merely saying that i believe my life to be meaningful enough to me to continue it.
Little bit of a ramble and not well argued but it could create some interesting discussion.
