Schedules: Realistic for me?

I'll be frank. I don't like schedules. I know they're necessary, and without them the world would be in chaos. What can I say? Maybe I like chaos. (My room is proof of that.) I don't think it's very likely that I would sit down at my computer at the same time every day. For one thing, I share this computer with my parents, and it always varies what time I'll be allowed to use it. For another thing, some days I am busier than others, and it's less likely that I'll be online. I am confident that I can set the necessary time aside to do well in this or any other online class. It just might not always be the same time.
