No one likes to be called as failure…we all want to succeed and we all want to be best in whatever we do..still we do mistakes and we pay for them…most of times we do them unintentionally..or may be we are not aware of what we are doing..as per our knowledge, experience we take the best decision and if it does not turn out wise, it is called as mistake..however, actually it is not a failure or a mistake because that is how you learn and grow wise or else even when you are 60 years old you will not be a grown up. I have seen even at that age people do not understand what they say or they do. They have always been afraid of taking decision as they cannot shoulder the responsibility and even at 60 they are unable to do so, as they cannot accept the very fact that i did that mistake. However, biggest mistake they have been doing is by not doing any. You fall and you stand again. If you have been falling does not mean you stop walking and not doing anything in life because you are afraid of mistakes is same. You have stopped walking in life. You are just sitting at one place. Now you can imagine. However, if you repeat same mistake then it is actually a mistake because same thing will produce same results and then you are a failure. A wise man would always learn from mistakes and grow wiser. You are allowed to do mistakes but not repeat. If you have done a mistake you know it, how not to repeat same results and that is called as experience as you know by doing such thing, what would be the consequences. You are wise enough to give lessons to others too.
Do not be afraid of falling and doing mistake, because that is how you go further and grow wise or else you would never grow up. You would never see what all you could do in life or else there would never have been any new invention.
