The line of reasoning doesn't go much further past this, for me at least. I draw and make comics as a hobby because it's super fun~
Although I'm also the type who, if it starts to be less fun or if I just need one, I'll simply take a break- thankfully I have other hobbies to fill those times but I find that the drawing breaks never last too long. Sometimes it's not even a proper break, so much as it is just drawing much less and/or just random stuff and not for a particular project or reason like usual.
That said there are both intrinsic and extrinsic factors beyond that that help drive me.
For whatever reason I always come back to drawing comics specifically despite, imo, only being a so-so writer & storyteller. I honestly don't have a real explanation for this but it's been ingrained in me since childhood. Like I never considered myself much of a comic reader until middle school when I was introduced to manga but despite that when I look back at my old drawings from elementary school and prior I had already been drawing comics so... I guess that's just a thing.
Comics are also more fun in some ways than standalone art for me since I feel like they encourage you to draw a wide variety of things. It's always fresh and interesting when there are different locations, and props, and characters, and etc.
Extrinsically, despite that it's hard to really take off in popularity, it's relatively manageable to gather a small audience (even if it's just people you know or whatever- non-artists eat up even shoddy art irl xD) and man is positive feedback in any capacity a rush. I'm glad that I don't need it to thrive like some artists, as it can get unhealthy to fixate on, but... I'd be lying if I said I don't chase that high a little bit
