But also, why end it? This is the perspective taken up by Absurdism
"Should I kill myself, or have a cup of coffee? But in the end one
needs more courage to live than to kill himself." - Camus
I would say even in the face of troubles, it only takes curiosity to have sufficient motivation to continue. So I think cultivating curiosity is very valuable.
The most convincing argument though I think, is that of mysticism. What really is meaning, what does why mean, addressed in the mystic sense of direct observation of our own minds and exploration of unusual ways to think and be, help to catch some of the processes by which we construct the world, and to realise that there is something unconditioned about our minds, something that precedes all the construction work of motivations and meanings. And we can situate our approach to life from there, once we become familiar with that place.
"When … you realize that you live in, that indeed you are this moment
now, and no other, that apart from this there is no past and no
future, you must relax and taste to the full, whether it be pleasure
or pain. At once it becomes obvious why this universe exists, why
conscious beings have been produced, why sensitive organs, why space,
time, and change. The whole problem of justifying nature, of trying to
make life mean something in terms of its future, disappears utterly.
Obviously, it all exists for this moment. It is a dance, and when you
are dancing you are not intent on getting somewhere… The meaning and
purpose of dancing is the dance."
"At the still point of the turning world. Neither flesh nor fleshless;
Neither from nor towards; at the still point, there the dance is, But
neither arrest nor movement. And do not call it fixity, Where past and
future are gathered. Neither movement from nor towards, Neither ascent
nor decline. Except for the point, the still point, There would be no
dance, and there is only the dance."
"And there might not be a sadder thing
Than watchin' Saturn lose her rings
And black holes slowly dancing in the dark
It's a song that they were born to sing
About the end of everything
Until it all goes up in one last spark
Everyone you love is gonna die
But so is everything so
wipe your eyes
You know nothin' lasts forever, but Lord, I try
everyone you love is gonna die
All the saints and sinners are the same
We're blessed and we obliterate
And that's how it was written from the
It's a song that we were born to sing
About the end of everything"
