Something to think about...this came from the book I'm about ready to finish called Simple Faith.

This is in the chapter about how we are always constantly worrying. The author is comparing "the natural world to our material lives."
No bird ever tried to build more nests or more extravagant places to live than its neighbor.
No fox ever got ticked off because she had only one hole in which to hide and rear her young.
No squirrel ever had a coronary because he failed to store enough nuts for two winters instead of one.
No bear was ever envious of another bear with a larger cave in which to hibernate.
No dog ever lost a good night's sleep over the fact that he had not laid aside enough bones for his declining years.
