It is easy not to care: do nothing and the world will crumble. Effort is required to maintain anything of worth. Doing good does not often feel so good.
There is satisfaction in knowing you have done well. But few escape unscathed from the results of good deeds. You either do it because you care, or you do not.
Those who can will do and the rest will criticize. Never mind having nothing to show for themselves. It is easy to watch, but hard to play.
Ease and sloth are meant for each other. They both eschew the difficulties of life. And they do not like anyone pointing out their inadequacies.
Life is hard, because the world is full of people who do not care. Those who do are wearied and prone to discouragement. It would be easy to leave them all to rot.
To do so would mean becoming them, and everything would grind to a halt. Those with ice in their veins should be wary. It is harder for a heart to keep beating, than it is for it to stop.
