When things go wrong, people love to say that it doesn't matter because at least you've learned a valuable lesson in life. To be honest there are many lessons about human nature that I wish I had never learned. Am I the only one to feel that way? Are all lessons good ones? I don't believe so, because if all lessons were good, all people would feel empowered by life and there would be no bitterness, anger or cynicism.
Personally, I don't need tragedy or 'little mishaps' to learn.... we are all born with common sense and know the difference between right and wrong. Sayings are cute ... but in the long run they don't do much to help in situations that shouldn't have been situations to begin with. Plus we can also learn from positive experiences, and I would much rather learn that way.
