I’m a student. I set deadlines that I know I can reach. The only times I have super short deadlines is when it will only take me a minute or two to deliver the gig. Otherwise I make sure that I have quite a few days to deliver, and unless they order early in the week, that means I’ll be able to deliver on the weekend instead of during the school week. Actually one of my classes is extremely boring and the teacher doesn’t teach, so I use some of that time to work on one of my gigs if I have any orders. It’s a drawing gig, so I just need a piece of paper and a pen/pencil. Then I just scan it in and deliver when I get home from school.
