I am also a freelancer, and to some extent it reminds me of being in college in the sense that there is always more to be done! Not studying, now, but writing. I also balance paid freelance work with my own creative (as yet unpaid) projects.

I miss many things from the office, chief among them the easy camaraderie. I compensate for this by attending in-person writers' groups which are my new "village."

I also miss having someone to ask questions of: "How do you say..." or "What's the command in Excel to..." or "How do you make a PowerPoint presentation landscape instead of portrat?" (especially after they updated it last time and pretty much HID that function for some reason) etc. But the chat groups of my writer friends also make up for this to some extent.

That having been said, I love the freedom of freelancing, too. But to your point, Jessica, it is a kind of deceptive freedom. The structure has to be there, or your work spills over into the rest of your life.
