Depends on the person and the amount of time you have. I manage to make a schedule out of everything I do. Basically I try to be organized as much as possible. The funny thing is I actually manage to spend time with my fans while I'm doing all of this lmao.
It doesn't take too long. Maybe two-three hours. Even then I have a comic system where I'm able to pump them out with quality. I'm actually making a script for my upcoming YouTube Channel and some Webm Collections to be like "If you find this funny, you should check out my comic".
Honestly, I'm just doing all of this so I can make a living out of writing. Nothing wrong with networking.
I should ALSO mention that you're talking to a person who writes lists for fun. I remember my Mom being bothered by the fact that I would write lists as a kid. Organizing stuff. BUT NOW IT'S PAYING OFF > : ).
Wax-on. Wax-off situation.
