I always have to do everything to perfection.  My wife calls me a perfectionist
Well, many psychologists not only agree that it has negative aspects, but also POSITIVE aspects! It's a multidimensional characteristic to have.
I think its slightly mixed with OCD.  I always have to make sure that I do everything exact, like putting all the dishes away exact
I can definitely lead to a sort of OCD where you strain compulsively toward goals that are unrealistic and unobtainable. And sometimes you may even measure your self worth by those accomplishments or lack of.
Im glad my computer allows me to erase and retype things, I can't imagine having to use a typewriter.  I would have gone through so much paper
In 1978, D. E. Hamachek argued that there were two types of perfectionism. Classifying people as either tending towards a normal level of perfectionism or tending towards a neurotic perfectionism. Which do you feel is you?
I think that I am normal, but who really knows lol 
Well it's all about self-esteem. A normal perfectionist are more inclined to pursue perfection without compromising your self-esteem over it, and you may actually enjoy chasing perfectionism.
