Hi!  What do you think about perfectionism as a topic in psychology?  Is it useful?
Seems like it has many positive but also negative aspects.
I agree with you.  What are some of the positive aspects?  Seems it can help in motivating people to do better.
I guess if they are the normal version that they still try to be perfect BUT it doesn't compromise their self-esteem.
That's true.  Perfectionism has two sides for sure - if someone beats up on themselves, the perfectionism is holding them back.  
They can very easily set themselves up for disappointment.
Perfectionism may be helpful sometimes.  I think like you said if someone can use it in a positive way, such as setting high standards, that can be helpful.
Yeah, it seems that it becomes a problem with they measure their self-worth by setting unobtainable goals.
