It's impossible for everyone to have the same way of processing things. It all leads back to perception, past experience, and maybe even the wounds of the heart. For sure, you can learn to process things in a more positive light and accept things faster. But like in the case of criticism, some people tend to victimize themselves and automatically be defensive.
It's all in the mindset. If you accept your flaw, you can improve yourself but if you don't, you leave yourself blind. So the way you process things can indeed change.
It's just my own opinion tho. And sorry for the late reply.
