Ah, having not just one BURNING IDEA but TWO of them is very exciting!! :D Totally get you on the fear of burnout at the same time. I think being aware/mindful of that possibility and looking out for it is already a big step in a direction to minimizing it.

Not sure if you saw this thread already: https://www.spiderforest.com/hub/thread?id=1651 I feel it's got some very relevant tips and perspectives that could work for you too!

Here are a collection of my immediate thoughts, bearing in mind (which I talk about in the other thread too) that everyone is different - ultimately you gotta try things and go with what works for you. (And for some people that can just mean taking a huge deep plunge with no idea of what's under the water. It works for some people!) Some of them are also potentially conflicting ideas, but they all have a grain of "this could make sense for someone" in them.

- Idea 2 seems like it's easier to start with - less intimidating/high stakes, fun, and you can dip your toes into and learn and figure out what works for you. Then you can use that experience and the skills you develop to make Idea 1 as great as it can be!

- If you honestly can't decide, why not do both? Start one, then try the other, work on them both as you feel like/have time for it. Doesn't mean you have to launch/publicly share both (or either) at the same time, but you won't know how it goes till you try them, and they are pretty different projects. The only way to start is by starting. (I talk about this in the other thread too.) Try starting both, see what works and what doesn't. It's not the end of the world and it's OK if you fail a few times, if you pause or stop a project, if you decide to restart/redo another. If fear of those things prevents you from starting, then the project may never exist.

I personally like having a few projects on the go, so that when I feel stuck or bored with one I can switch to another. For personal projects, the only "deadlines" I have are the milestones I create for myself.

- Managing your own expectations. Pace yourself, figure out what's important to you and focus on things that make sense for what you care about. People may have different priorities for their projects and I think it's a good thing to figure out where you yourself stand so that you don't end up stressing yourself chasing someone else's idea of success, especially if they can seem similar. What do you want them to be?

For example, these three goals: 1) to turn an idea in your head into an actual story; 2) to share your stories with the world; and 3) to get "professionally published". They may seem like the same goal, and they can be overlapping and all exist, but they are not mutually inclusive. Getting published may SEEM like an obvious end goal to achieve the other two things, but that's just one option. For instance, I don't care that much about being professionally published. I do care a lot about 1 and 2 though. And I have another friend who actually doesn't care much about 2 at all, they just want to make things and see that they can make them. So, what's important to you? I personally think that helps a lot in providing a compass on your journey.

- Some practical considerations. Bear in mind cause and effect - decisions you make have ramifications. This applies to a lot of things, but right now I am thinking about the fact that art styles that work for illustrations aren't necessarily the most appropriate for long form storytelling. For instance, something that looks super cool and gorgeous may feel infinitely less cool and gorgeous when you have to draw it over and over from every angle. A character with tattoos all over their body, a background full of books and painted tiles and fine wood graining on every surface as your main setting... This isn't to say you can't do it, just to be aware of the choices you are making and what that means for your workflow.

- The above are some principles, but I do want to stress (again) that I can't really tell you what you should/must do, or what you should/must avoid. I mean, one thing that seems super basic and obvious that one should do is plan and create stylesheets for all your characters and all your locations so that you can draw them consistently, but I have a really hard time doing this so 90% of the time I'm wasting time going back through old pages trying to remember how I did something. But I've already drawn a bunch of comics with this approach so oh well, hahah. (I am trying to do more "proper" stylesheets in my current project though, haha. But just saying, just because it's something everyone knows you are "supposed" to do, doesn't mean you have to do it. Or that everyone does it. I definitely know I'm not the only comic artist with a hard time creating "proper" stylesheets upfront.)

- I lied, I thought of something that is probably universally applicable. Remember that comics are a mental and physical effort! Make sure to take care of your health so that you can keep doing what you love! Take breaks and do stretches, stay hydrated, try to make your setup ergonomic!

Hope this is helpful!

I will echo much of what Maiji's stated.
Each person is different. I took the "big plunge" turning my novels into graphic form, (there were a lot of firsts in Plague: First time working with a tablet, with digital, with transforming words into images effectively. It was a huge learning curve)
But it's a huge time commitment (it took me 11.5 years to complete the story), and that may not be feasible right now (or possibly not at all). So if your time investment is shaky, or you're not sure about it, you may want to start small and work up to the larger, more intensive time sink. This will give you a better idea of whether or not you think you can stick with it.

(BTW I do TWO full time webcomics these days... so I've been at things for a while and will be for a while longer.)

A few things I learned the hard way:
*Readers don't need to know what everyone's thinking all the time (IE limit internal dialogue) - this has the added benefit of retaining mystery to help build/keep interest.
*That 30 page chapter in your script/novel, may not take that many pages to put out graphically because the pictures carry much more weight.
*Build as much buffer as you can before you start, this greatly reduces stress of "I've got to get this done before my update day." (THIS IS SO HARD FOR ME!)

Totally seconding maiji and Darwing on the point of keeping the scope of your comic managable at the start. I remember having an “I can totally do this!” feeling when starting out my first “real” comic, then a dozen pages in being so very fed up with drawing the same detailed characters and backgrounds over and over and over again…

So if I had to give just one tip, I’d suggest starting a comic with a scope you feel you’d be able to produce consistently, week after week after week. While doing that, and when you feel you have the time, you can start planning another project in the background, all the while developing your comic art skills with your first project.

Delphina on the other thread mentioned setting a time limit, which I think is very useful on the consistency goal. For example, let’s say I set myself 1 hour a day, 6 days a week to produce one comic page. That limit would force me (in a good way) to choose a quick enough style and easy enough format for my comic, all the while keeping the workload light enough that most Life Happenings couldn’t disrupt my page-per-week schedule.

That’s exactly the limit we set, and kept, for our Realm of Owls comic. A lot has happened over the last seven years, but the page-per-week schedule has kept to this day!

Oh, and about the character/location stylesheets that maiji mentioned: they are definitely really useful! For the RoO, I have a giant digital canvas file with characters and locations screenshot straight from comic pages. I keep that file open whenever I draw the pages, so that I don’t have to spend time searching for references from my own comic!
