Failing to learn from failure

You must learn from failures; success is going from failure to failure without losing the hope.

But what if someone fails to learn from failure. Is it not a failure again. So, if some point of time if that person realizes his failure to learn from failure.

Failing to learn from a failure is not the biggest obstacle; failing to identify that failure is. 

If you have failed to learn something and apply course correction from your failures; go back and learn. Do not give it up; get something from failure. Isn't it true that you have tried and that is the reason you are a failure; not many of them have the guts to even try.
