It can be self-destructive and time wasting as perfectionists often procrastinate to avoid doing important tasks in what they see as a substandard way.
They push themselves beyond the normal limits to achieve their goals and people are sometimes surprised by what they can accomplish.
Perfectionists do not deal well with pressure and close deadlines, particularly when the work is important, as they feel they do not have enough time to make their work 'perfect' and therefore be happy with it.
It can be both a blessing and a curse.
Perfectionists are not the same as those who suffer from obsessive-compulsive disorder (OCD), although they can be obsessive about their work.
