It’s not like that. First of all, you need to understand what you did so far. when you accept your failures and mistakes, then only you will realize who you are and why you did like that. after that, you can go for the success. if you are not ready to accept your mistake, you never see even the little bit of success.
If you are a person representing a company/any person, definitely the reflection go to the relevant person /company. not you. That’s why we need to care about that. Mistakes can be allowed. But don’t do the same mistake again and again. It’s not good for your reputation as well.
And also Everyone can point out the mistakes according to their experience. It doesn’t matter if they did the same mistakes in their previews life. If you realize your mistakes, you never think in that way. Please take it as an advice and correct your mistakes. Don’t take it any personal. Be humble and the most important thing is don’t compare with others. Be your self with your own style.
I hope you can understand my points. If you need any further advice or clarification, please ask me.
