>Therefore man was created single in the world to teach that for anybody who destroys a single life it is counted as if he destroyed an entire world, and for anybody who preserves a single life it is counted as if he preserved an entire world.
(Directly from the Mishna in the Talmud Yerushalmi)
To me that never made sense. If the world is really ending, there is no point in planting a tree.
It only made sense as in, you never know if the world is really ending. So assume it is not and do the right thing, even if things seem dark. Everything we do matters. Always.
