Is it normal not to take criticism?

You mean you don't know how to take criticism? If thats what you mean, I have trouble taking it too sometimes. And it does feel like they're altering my character as an individual. I hate it.

I don't think there's enough information in the original post to provide the right feedback.

Maybe he's implolite, rude, and mean and people criticize that. Maybe he's surrounded with overbearing people who think he should be more like they want him to be. We don't know because he didn't say.

Dont take changing as disadvantage, in 40 years i think, 90% of your bodys atoms are different. Of courde this change doesnt happen in one day but you have to take changing as natural process

Criticism is a way to realise your faults and to adapt.by ignoring it completely you are only asuring that you wont move on and get smarter.

Whenever I'm criticised, I try to work out why it happened. Sometimes it's me (in which case I learn something about myself). Sometimes it's a failing in them (in which case I learn something about them). Either way, it's a win.

Are you Sarah Palin?

Change is inevitable, and yet we all stay just the same.
