I find it freeing. If there was an absolute meaning. Something we were supposed to do. For example multiply. There is our "free will" (another concept for another topic) for no use.
So you can do whatever you want, wherever you want and however you want it (with some obvious constraints and consequences).
You can do as much "good" (in your definition) as possible or bad as possible. You can just carpe diem whole life, or you can do something you feel is more interesting/important.
