It's absolutely right that "Mistake is always Happened to Doer". In Khmer means "កុំហុសតែងតែកើតឡើងចំពោះអ្នកធ្វើ". So why you have to do it if the more you do the more mistake you have? In the saying we want to tell you that mistake is your experience and experience will teach you to the right one. For those who never do it, they will never have a mistake but they will never know or learn the new things as well.
So keep doing your great jobs and learn from your mistake. Remember mistake should be never happened on the same case again and again. If so, it's your fault because you haven't learned about your mistakes.
