It only doesn't apply for business, but for every day life. When you do mistake, I believe you're not only doing mistake. There are many facts that run in your vein. Let me list out main facts that I want to clear easily. - thoughts of improving/not repeating When you do mistake, it's the common thing that many people regret not to repeat again or improve. Like from daily life to business, it is implemented. - motivational thoughts Especially talking about business, you're inspired that you failed due to mistakes and won't let it happen next time. - going to be perfect The more mistake you do, the more conscious you're. That means you won't repeat mistake next time because you've already faced it. And you're to the perfect to do the business or anything efficiently. At last, I just want to add something that is, people are also sad and unhappy caused by mistakes, but I believe One should be inspired by doing mistakes, and never be afraid to do mistakes.
