Sometimes I liken my work to ironing. A lot of what I do is trying to smooth out "creases". Correcting spelling mistakes and typos, making sure that names of people and places are spelled the same way every time they appear, making sure we have consistent vocabulary and so on. Sometimes it is frustrating to come across old drafts which are very "wrinkled", but there is a certain satisfaction in working on them and seeing them become flat and pristine.
The ironic thing is that in the real world I hate ironing!
