Don’t go the extra mile just for a job. If you die trying you can always be replaced. In the end, death is inescapable.
Be picky which with jobs you choose to do, make sure it is not taking a ton on your health, and always plan for your old age just in case.
That part where you said "death is inescapable" should remind everyone of the fruitlessness of life itself. Everything we struggle to acquire here, will at the end, not matter. It's all vanity upon vanity. We've to be smart enough to know that there should be cool off moments in life where we take a chill pill and relax a bit. We've to use our head or someone else will use it for us.
