I've run two comics at once before, the trick is a huge buffer. I've only got one going right now, but that one's scheduled weekly to the end of June 2025 currently, and that's about normal for me-- in fact, a few comics were completed on my end before I even started posting hah;;
And, when I run two comics at once I usually spend months-- if not a year-- creating a buffer for that one too.
Then, just make sure your weekly workload is something you can manage on average. If you over work yourself, you're gonna fail so if you don't think you can really come up with the time realistically I'd suggest not to bother. If some weeks get busy, well, you got over half a year in the queue so no worries, but as long as you got the time for 2 chapters a week on a normal week (or whatever your post schedule is) you should be just fine.
Really, it boils down to if you can hack it, you can hack it. If you can't, you'll have to sacrifice other things in your life-- so make sure that's a reasonable and realistic and healthy thing to do if you want to try. If you can't, then you just don't have the time and you'll always have more time after your current comic. Don't burn yourself out.
I do it by not having much of a life, frankly. I see a friend maybe every half a year. I barely visit family. I work, but I take the bus and use the ipad to draw so I can work on my comic to and from work. On my breaks. When I get home... The only other hobby I have is writing, which is taking up my "second project" time slot right now instead of a second comic lol. I know it's not really the most realistic thing for most, so. yeah. That's all I really got.
