I just heard this story:
There was a lion, a donkey, and a fox that went rabbit hunting one day. At the end of the day, they came together and there was a big pile of rabbits in front of them. The lion said to the donkey, "Why don't you divide the rabbits fairly among us." So the donkey made three nice piles of rabbits at which point the lion killed the donkey, ate part of him, and threw what was left on the pile of rabbits.
Turning to the fox, the lion said, "Why don't you take the rabbits and divide them fairly between the two of us." The fox made a big pile in front of the lion and took one scrawny rabbit for himself. The lion asked, "Where did you learn to count so well?" To which the fox said, "I learned from the donkey!"
That's called learning from other people's life experiences!
