Let's go!
I'm currently living rent-free in an unoccupied student room in Edinburgh (it's out of term here, and I'm living with friends). I'm spending most of this month enjoying the Edinburgh Fringe Festival[0] (I saw 7 shows yesterday). The remainder of my time goes on Open Source/contracting work.
Due to the Fringe, this month is unusual and I'm not satisfied with my open source activity: it's mostly code reviews, force-multiplier work, mentoring and small changes, rather than larger architectural work or features.
Financially: In the UK, the minimum wage is £9.30/hour. This is around $20k/year. Open Source work nets me between $10 and $1.50/h via Open Collective (donation funded), plus I've previously listed my hopes for the next month[1]. I want a multi-monitor setup for my next 2-week project, and that's not feasible to travel with.
Am I OK? I am for now. Although my lifestyle offers me a lot of flexibility, it isn't feasible to start a family or hit the traditional 'life goals' while living in this manner. It's a shame to have to fundraise for small personal projects ([0] https://en.wikipedia.org/wiki/Edinburgh_Festival_Fringe
