Failure my best teacher

Failure has been my best teacher so far. May it be academics,sports or relationship ,I have seen failures and nothing could have taught me better than what failures have done. I have grown up stronger each time.Have emerged much more positive and optimistic.Every mistake made when taken as a lesson learnt would be very satisfying at one point of time in life. If you have not had failures then you have failed to understand life. As I would say the spice of life would be missing .You fail to rise.More the failure ,sweeter the success
