I've been working on side projects for the past 3-4 years on whatever caught my fancy and have thoroughly enjoyed experience and the rabbit holes some of them have led me into. I like it and I feel I'm at a point where I want to get more people involved in side projects. But, any discussion about these projects with (nearly) anyone ends with 'How will you make money'. I don't have a way to avoid or answer that question without losing people's interest. I'm curious about how others handle that one.
To be clear, I do not work on side projects for money. Neither do I intend to. Thats what my day job is for. I just want to involve more minds interested in similar things that I'm racking my head against.
guerrilla knitters. billboard spraypaint agitators. music makers in pubs. choirs. scratch orchestras. the guy who makes kites or the professor who shows kids how to do astronomy on street corners.
the mens-shed movement is about older people (yes, I know the name is offputting but they aren't all men actually) who are bored and have skilz. Also, not about money.
likewise tool libraries. or, computer upcycler schemes for the unemployed: these are people who do things because they think they are worthy (tm)
