Local Chambers of Commerce run a lot of courses and support for starting businesses and others - and the advice I've heard time and again for hose interested is for the employed to balance it with self employment until they can move on. I don't think the current rhetoric that dismisses employment & treats self employment as the only way to be free really has people's interest at heart (and largely seems to be to sell courses that the Chambers of Commerce likely has better and more affordable options for).
I'm both employed and self-employed. In both I'm relying on people and I have no issue with that. Even using this site involves relying on others and I don't get why that line is so often tied into self-employment.
There are many reasons I am no longer only self-employed. One is that doing mainly computer-based work had become absolutely horrible for my physical and mental health & was not working anymore with my disabilities. In the last year, I did a career change intentionally to increase my employed hours that cannot be WFH and has limited computer use mostly for health and wellbeing reasons. Now my daily movement needs are nearly entirely met by my work during the week.
Another is the I am the type of person who is more than happy to help others for free, which works less well in self-employment.
Another is I'm the type who can get obsessive about a project and work on for free - and I'd rather just do it that way at my own time rather than fitting it into a business model.
In my employed work, I work with a lot of self-employed people who will tell me how they were up very late working on this, that they got up so early to get there, how frustrating it is that they put in all of that and we're not going ahead today... I get it, but I also accept that putting in that work & the wear on our health often doesn't have that pay off.
There are many others, but largely it comes down to finding what works well for me when it comes to work. For me, it's both employment and self-employment that works around my wellbeing and how I work.
Virtual PAs for example is a profession/job that didn't even exist 20 years ago.
I think it's closer to 30 years ago now - I was doing it 20 years ago, and around the early '00s is when I started seeing the courses and agencies popping up at job fairs and everywhere else. It was a lot rarer then, but it existed and gaining traction then I think as broadband became more common in businesses.
