Failure is the mother of success
As some prudent man put it,"Failure is the mother of success".If we consider it from the deep layer,we would easily find out that failure happens much more frequently than success does.What's more,it's with the experience we learned from these seemingly unhappiness that we can climb up the mountain of success.
However,different people may have different opinions and attitude toward it.Some take it as a suffering process,while others might make use of it and finally succeed after failing over and over again.
As far as I am concerned,I believe nothing compared with failure can contribute this much to our way to succeess.Settle down,make some reflection on where the problem is,you will certainly get better and better.
