Why I Failed

I have always failed, I have tried many different ways does not matter how hard one too, though I failed many times I try, why is this happening? all the lessons taught to me, I go, but it still fails .. I still do not understand why it happened.
Actually I learned from the failures that I confronted, it made me full of experience. Now I became more bold and not afraid, I was able to produce many of the best ideas. I used to be praised by my friends. They are very proud of the courage and the experience that I have right now.
Now I just understand, why I have failed before, apparently I need the knowledge to fight before I continue to fight the real fight.
