Hm, for comics I'd say I enjoy most of the process. Each part of the process takes a different mindset and I enjoy switching between them.
I'll break down the steps and rate my enjoyment:
1. Plot/character ideas - I literally cannot stop coming up with these, all the time. Scenes, characters, concepts, all that arises naturally from the environment. These are fun to think about, fun to talk about (if you have a good listener).
2. Preproduction - this stage is a lot of fun, too. Exploring ideas, working out what things look like, doing concepts for new ideas, this is another thing that I will never stop doing.
Only the needs of being a human animal and existing in a society will stop me from 1 and 2.
3. Writing/storyboarding. This part is fun, I usually do the writing of each chapter in a week or so. During that week, I can hardly think of anything else. I'm constantly thinking about how each panel and each page should go, what the next line should be, symbolism, managing pacing, all those things. I love problem-solving and managing variables like that.
4. Preliminary sketching. This part's a bit tedious, working out in-detail the composition of each panel. I try to make this step go as quickly as possible, but it's a lot of problem solving, too. I do the lettering during this phase, which is always a pain.
5. Sketching - this part is great, it's fun to see the drawing come to life. This is the first part that can get me into the creative "flow" state where I'm focused entirely on the act of creation.
6. Inking - I don't have to think hard for inking, I like to put some music or videos on and try to get into the flow process. Time passes quickly for me here.
7. Painting - just like inking, I'm not usually thinking too hard, I just try to get into the flow and stay there. This phase is the most frustrating to be interrupted in.
8. Scanning/digital touchup - I don't enjoy this much, but it usually doesn't take too long, at least.
9. Posting/Marketing - This is the most tedious and least natural part of the process for me. Finding the audience, posting around, that part's the least natural part for me. Also, I usually care very little for my paintings when they're done - once the thing is done, I'm also done with it.
That about covers it for me. If you left me alone in a shack in the woods, a cloistered cell, or some other place where I don't have to do any life stuff, I'd still be making art and stories, usually as comics. That's not really a chore for me, although since it is my hobby rather than my profession, I don't usually get to a place where I've just been doing art all day and don't feel like doing any more when I get home, the way standard pros get.
