Learning from other pple is indeed a better way... but for humans.. we seldom learn from other pple.. For instance, we haf been told not to touch the kettle when it's boiling water... but still there are pple who do that...
However, falling doesn't mean that one will learn too.. It's not necessary a bad thing.. doesn't mean that it's a mistake too.. Take it as a new chapter in the textbooks. For example, Edison didn't take his failures in inventing the light bulb as a failure, but as something that he has learnt... He learnt that his hair cannot light up and neither does it conduct electricity...
