Are we learning form our mistakes?

Are we learning form our mistakes?
=======================
With every mistakes we must surly be learning. 
=======================
Observing the history of human beings
we will realise that this statement is not at all true.
=======================
This is why history in most cases repeats itself.
=======================
This is why you cant never make the same mistake twice,
because the second time you make it ,
It is not a mistake ,Its a choice
=======================
"If history repeats itself, and the unexpected always happens, how incapable must Man be of learning from experience."
=======================

=======================
إِنَّمَا التَّوْبَةُ عَلَى اللّهِ لِلَّذِينَ يَعْمَلُونَ السُّوَءَ بِجَهَالَةٍ ثُمَّ يَتُوبُونَ مِن قَرِيبٍ فَأُوْلَـئِكَ يَتُوبُ اللّهُ عَلَيْهِمْ وَكَانَ اللّهُ عَلِيماً حَكِيماً
=======================
4:17 Allah accept the repentance of those who do evil in ignorance and repent soon afterwards; to them will Allah turn in mercy: For Allah is full of knowledge and wisdom.
