Failure is the mother of Success

People always say "Failure is the mother of Success", especially Chinese. This chinese idiom is usually used to courage people not to give up easily when failed, because failure helps a person to learn from his mistake.

Well, have you ever think of slightly a little bit more than that; if, the Failure is the mother of Success, then who is the father?

Honestly speaking, I have no idea who the father would be. But I've got some opinion saying the father would be "Hardship" and the other said it's "Chance". What do you think?

"P" said the father would be Hardship because father and mother have different roles in a family, especially in raising a child. Father need to be working hard to earn money for the family whereas the mother would be taking care of the family and children at home. This sound normal for olden days, but nowadays mother also take up the responsibility to go earn some money for the family. So, where is the ideal? Then "P" said mothers nowadays are great, they go work and also taking care of the family at the same time, so they earn the credit, children are more closer to their mother.

Then another friend "M" said the father would be Chance. He said by chance, Thomas Edison could successfully invent the bulb, if there was not chance available, he would never succeed no matter how many effort he put on. Also, Issac Newton will never come up with his Newton's law if he had no chance to observe an apple fall from the tree.

I personally agree with the idea of "Chance". So in short, i think "Men are Hardship, Husband is Chance."
