I'm currently revising the novel that will be my MFA thesis. It's a bit of a monster -- 125,00ish words, some 400 pages. The longest I've written. It's very difficult to manage.
When I've got specific feedback for a book -- as I do for some portions of this one -- I like to read the work through these readers' eyes and imagine what led them to say what they said, and how I might alter the structure to please them better. I also tweak the sentences constantly.
When I don't have specific feedback for a section I prune a lot and change words and images, and prune more, and maybe add one sentence, but it's harder for me to perceive the work holistically enough to make larger structural revisions. I tend to write fairly complete drafts (in part because I fuss with them so much as I'm writing my "first" draft) so that explains this in part, as well. But it's frustrating! I want to transform my work. I want to take quantum leaps. Etc. But maybe that's something I do more in-between texts than within them. I'm not sure.
How do you revise? Does it feel good? I try not to feel anything about it.
