It's true, and you do get into "If I take the week off I'm losing £X!" headspace sometimes. But it's important to remember that if you don't take that week off, you're more likely to burn out.

And it's also important to remember why you got into it in the first place - being able to take significant amounts of time between contracts was a big part of it for me. I intend to take three months downtime a little later this year.
