The insupportable labor of doing nothing.
Sir Richard Steele insupportable quote

I have absolutely no pleasure in the stimulants in which I sometimes so madly indulge. It has not been in the pursuit of pleasure that I have periled life and reputation and reason. It has been the desperate attempt to escape from torturing memories, from a sense of insupportable loneliness and a dread of some strange impending doom.
— Edgar Allan Poe

A man of genius is privileged only as far as he is genius. His dullness is as insupportable as any other dullness.
— Ralph Waldo Emerson

Nothing can render affliction so insupportable as the load of sin. Would you then be fitted for afflictions? Be sure to get the burden of your sins laid aside, and then what affliction soever you may meet with will be very easy to you.
— insupportable quotation by John Bunyan
