"In the end everything will be okay. If it's not okay, then it's not the end". Maybe my perspective on life allows me to think of this much more philosophically than was initially intended. For me, it implies an "okay" even when the worst - say death - were to happen. The universe, so unapologetically unaffected by my absence, would still experience peace and calmness, as would I, regardless of an afterlife. Even when the worst comes, for me, humanity, earth, etc, calmness and peace will eventually settle.
Plus, after thinking of all the above, any trivial obstacle I may have encountered in my ephemeral lifespan is suddenly insignificant, allowing for a clearer mind and wiser decision on the matter with a MUCH lighter-hearted approach. It works every time.
One of my favourite quotes comes from Mikhail Lermontov's A Hero of Our Time (itself a fantastic book):
The worst you can do is die, and you have to die sometime.
Sometimes it's quite soothing to remember that at some point you'll be dead and all this will be over.
I feel the same, but closer to "In the end, everything shall come to rest." You, I, everyone and everything we know, will end. Nothing we can do to stop that. However, until things end for us, we will continue to live an exist. That's the flip side; it's not over till it's over.
