It’s true that many people learn after failure or making mistakes. For me, the time I started the primary education. We did examinations after finishing midterm. I was not performing well in all exams so that was hard for me because it was the first time and started with a failure. It's easy to give up. After that my parents told me that I have to start learning at home and making correction of that examination so I start that learning and getting support from my brothers on the things which I have not understand, so I started studying hard because studying hard is a way of making me successful and pass my examination also to not give up and focus on what I am doing in order to be success. After the school opened and started learning every day, then the time of examination started so I did my examination and passed all my exams. I was so happy about that and also my parents were happy for me. So, the lesson I get is that if you fail don't give up but find the cause of your failure and then work on it you will be successful.
So, my advice to all people is don’t give up even if you fail but find the causes for your failure and correct it.
