How do you deal with criticism?

It depends on the criticism.
I really love constructive criticism, where I'm told what I need to improve on and how to go about doing that.
However, I hate criticism where people point out my so-called flaws just because. Especially where my personality is concerned or other things that I can't help.

It's constructive criticism, then take it happily and life goes on. You get better too from it, so take it in.

I usually completely brush it off.

Depends on the criticism.

I just shut up and take it with a smile. :)

Depends on who it comes from..like if its a stranger you're gonna be like uh you don't have a say in this but if you're close friends with them maybe you should try to listen because if they have an image of you doing whatever it is you were doing you probably should make sure you're not in the wrong

ignore it.
life goes on.

You listen whether the criticism made against you is just or not. If it is, try your best to correct it. If it is false, don't pay any attention to it.

"If I were to try to read, much less answer, all the attacks made on me, this shop might as well be closed for any other business. I do the very best i know how - the very best I can; and I mean to keep doing so until the end. If the end brings me out all right, what's said against me won't amount to anything. If the end brings me out wrong, ten angles swearing I was right would make no difference."

- Abraham Lincoln

It depends.

.....wit.....

It depends....

When I receive constructive criticism it makes me really.. Happy? I love finding ways to improve myself like writing, drawing, etc. If someone gives me advice on improving than I am all ears.

What I don't like is when people criticise who I am. I know that I'm not perfect and I honestly don't need most of the kids at my school pointing that out to me on a daily basis. Atleast I know I'm not perfect like some people who ignore it and act like they are the hottest shit around...

Constructive: Take the advice and continue.
Hate-for-fun-criticism: Depending on the grammar, I will be either sarcastic or down-right insulting.
