Why put an effort? Why do something if "matters", "make sense" do not really exist?
Why not put an effort? Why not do it anyway, why not try do do something deemed grand in society just because that is the thing that can be done, maybe because not really anything is left to be done is life. To experience different things in life. And maybe to experience life as it is, both positive and negative emotions. To know the world, the emotions, the events.
Other thought:
Maybe failures and bad events are not that bad?
