Because we are terrified of the day that we die and are no longer able to appreciate the depth and scope that is our lives on Earth.
So terrified, as a matter of fact, that many of us spend the entire time we are given here worrying about tomorrow, the afterlife, and million other things that steal from us the the very life that we are so desperately trying to hang on to.
We all die. It’s not morbid. It’s not negative. It’s not nihilistic.
It’s a fact. Quit wasting your lives and start fucking living them.
