To provide a brief explanation of what "the Absurd" is has been the subject of much learned research and writing, none of which has resulted an explanation that could be considered brief. Essentially, according to Camus, humans feel their life has meaning, but when faced with the fact that we ultimately die, that life may have no meaning. This paradox, and struggling with it, is "the Absurd".
I've often felt that profound desire to give up an endeavor, or when faced with a difficult decision, to become so agonized over it that abandoning any course of action seems like relief. However, even in moments in my life where I have faced such an internal conflict, I'm forced to acknowledge that my life does have meaning, and that giving up in any sense of the expression, will not aid me, either in the present or the future. Although it can be difficult, I usually push past whatever personal conflict or internal turmoil, simply because I'll be better off for having abandoned that line of thinking. In doing so, I may not come to a satisfactory conclusion or course of action, but I do see one reveal itself to me, if not immediately, then over time. This consistent resolution of the affairs in my life has allowed me to be at peace with whatever may come, be it absurd or not.
