Here is one thing I learned over the years.
There are people of type A who believe there actually are meaningful things in life. This belief requires to acknowledge that there are also meaningless things. And yes, sometimes identifying those things can get a bit depressing.
There are other people, type B, who believe there are no meaningful things in life. This same statement can be given a positive spin by negation, but the essence remains the same. This is the type that lectures everyone on how subjective and relative everything is, like it's some kind of revolutionary idea we have not heard before.
But that's not it. What I really learned is that having a conversation relating to meaning or value of anything is entirely pointless if you're speaking with people of type B. Eventually, they will fall back on stating the same core belief (the one I just described above) in a myriad different ways.
And here is a question worth asking. If people of type A can have a productive conversation about things that type B considers non-existent, which belief system makes more sense?
