I was being sarcastic, actually. Introspection is a good thing, and it isn't necessarily self-criticism.

Introspection is confusing and tiring and tends to make one like themself less. Why would I do that when I could be doing things I actually enjoy? 

That being said, I can see it working for some people. I have quite a few friends that are very self-reflective and they tend to give the best advice.
