A man died and found himself in the most beautiful place he could imagine. Nothing but beauty, peace and quiet. While he was drinking it all in, suddenly an entity appeared and told the man that it was his guardian angel, and that he could have anything he wanted, in any amount for as long as he wanted it.
The man pigged out on food, booze, gambling and sex.
That went on for 6 months and the man made a proper fool of himself. But, eventually, he came to his senses and realized that his existence was worthless. Calling upon his guardian he said, "This is all very nice, and I have enjoyed it all very much, but I need something to do that has some value. Give me a job."
His Guardian said, "That is the one thing you can never have."
In despair the man howled"What? you mean I must spend eternity with nothing worthwhile to do"?
Guardian says "I'm afraid so."
Man said, "I may as well be in Hell."
Guardian said, "Where do you think you are."?

This is one of my favorite short stories.Without goals and challenge we are worthless.
