Thanks, Suzie. Some worthwhile suggestions there.

Based on my limited recent experience, the best of the available freelance sites seems to be Upwork. It can be frustrating, though. I've had to spend a significant amount of time applying for multiple jobs every day before I started to get anywhere, and the pay isn't always the best. But my hope is, as I get more work, and become more in demand, I can start to put my prices up and become a but more picky about what work I take on. It's very early days yet, though.

I think it's also important not to burn yourself out. At the moment, I'm being very careful to manage my time properly and not overstretch myself on any given day. As one productivity expert said, never do more today than you can completely recover from by tomorrow. Steady, consistent action is the best way, and it's all about balance.
