Hmm, yes that's good advice.

Mostly Linux and open source computing, from a system administration perspective. But also environmental activism, economic analysis, politics, music, writing, crypto. I have a wide range of experience and interests and it's difficult to channel myself into one specific thing.

I can overload myself quite easily. I would like to be doing lots of different things to earn, very difficult in practice though.

In what field do you freelance in?
