I don't even really know what it is I do for a living - the level of insecurity is very, very high. You're making a lot of money, getting a lot of accolades and positive criticism for something where you don't even know what you're doing.
If I spent all my time criticizing myself, I wouldn't be able to function. There are actors who theorise till the cows come home. I haven't the patience for them. It's maybe shallow, but that's why I'll never be part of the acting set.
Like many people, I think I'm my own worst critic. And I think I take a lot out in an internally abusive way, looking at how I measure up, which usually was never enough. I never, never was as good as someone else.
The clear problem of the outlawing of insult is that too many things can be interpreted as such. Criticism, ridicule, sarcasm, merely stating an alternative point of view to the orthodoxy, can be interpreted as insult.
