Perfectionism - Boon or Bust?

I don't understand. Can you give an example?

HI,
Perfectionism, as explained in this link:
PERFECTIONISM--UIUC Counseling Center

Really is a mental illness. The words "gifted ones", to me, means someone who has a "gift", such as more intelligence toward any particular subject, thinking, or is far above the average person. They can use the human mind to much more extents that normal.
Personally, a perfectionist is mentall ill, and it's not really a gift. Trying to be perfect in anything anyone does, and I do mean Anything, means always fighting an uphill battle. Goals for these people are not realistic, and they are always trying to achieve the impossible.
No one is perfect, but to think one has to be, is a great disadvantage in everyday life. A person such as this could accomplish much, much more with their lives, instead of spending such a great deal of time trying to prove themselves in every instance, being "perfect".
Just my thoughts. I have had one friend in my lifetime, so far, thinking everything he does has to be perfect. It's no fun even being around a person like that. I really haven't seen this person now for years....guess we aren't "friends" anymore.
