Claudine C asked the internet for advice on working from home. I have some opinions about that.

• Stay warm. Proper offices are well heated or air conditioned, but your house probably isn’t normally warm during the day, if you are not normally in it. You need to think about how you will keep your work space warm, especially if your work is mainly sitting in front of a computer. Sitting still means you get cold quickly.
• I second the tip here about investing in a good chair. Spend a long time choosing one, and spend as much money on it as you can afford. You’re going to spend a lot of time in it.
• Keep the office tidy. This is the thing I struggle with; my office tends to be a dumping ground for crap that I’ve cleared up from the kitchen or the living room. Books, cameras, unpaid bills and other bits of paperwork just get chucked in to be “dealt with later”. Then it all ends up in a big messy pile that I find very offputting when it comes to creative thinking.
• Get cupboards, not shelves. You need to store your stuff but don’t have it all on display. This is another mistake I made; now I’m looking for cupboards to fit in the space where my shelves are.
• This pros and cons article hits a lot of nails on their heads. The low overheads and improved flexibility things are obvious. Dealing with distractions and coping without human contact are very personal issues. I can ignore the phone, and work with or without music playing depending on the kind of thing I’m writing. The bonus of working by myself is that if I want to listen to “Bye Bye Pride” by The Go-Betweens at top volume, I can, and I won’t disturb anyone else. In other words: you can make your own distractions without distracting others.
  As for human contact, I make do with IRC and iChat and chatter outside the school gates, and that’s fine for me. If I really need company, I’ll arrange to meet my wife or a friend for coffee or lunch.
• Do have a room that’s just for work, not a laptop on the kitchen table. That said, sometimes you can take your laptop to the kitchen, just for a change. Being freelance rocks.
