Digging our heels in deep here Phil ;D
I did have an office 2007-2009 but the overhead (~?500) a month was ridiculous. I just work from home since 2009 and I'm saving, plus I can claim back on expenses such as rent and what not. It's awesome being able to talk/see the kids whatever time of day and just creep back to my desk whenever I please. I do have a strict routine of 12-14 hours a day Mon-Friday, sometimes weekends included if it's a big job.
Being self-employed is such a roller coaster, one minute you're way up, the next it's rock bottom and the entire journey you never know how much/when/where from pillar to pillar. That's part of the excitement though.
At the top of this year, I found a new platform for online education and I started teaching kids and adults alike how to develop computer games with no programming at all. I've had the privilege of working closely with a global company (I won't namedrop) but they develop awesome software for all ages to develop games and applications in with no programming, I'm quite close to the company itself (although not part of it) and it's a fantastic community with huge potential laying before it.
Do you still do any programming at all?
