See, whether you accept or not, the criticism has already happened, isn’t it? You are left with no choice. Only after someone has spoken, you find that they have criticized you, right. How do you know before they speak? Before someone criticizes you, you don’t know. After they have criticized you, it is already done.
What is the option you have? Okay, don’t accept it, what will happen to you? You will become more miserable. So if you are intelligent you will accept it, if you don’t want to be intelligent you can suffer for some time. That is the only way you can do it.
