I was thinking this recently due to various life events...
What would you do? Any niche areas??
If this is something that you're seriously considering it doesn't matter what I, or anyone else, would do.
It only matters what you do.
I find this very interesting.....
Categorized them into jobs of different responsibilities/ stresses.
Low stress = flooded market = cheap start up costs.
Dog walking, gardening, delivery driver. Many with van.
Medium stress = higher skills = greater rewards
Carpenters, Builders, wood burner installations, sand blasting etc etc.
Higher stress, risks and reward.
Plumbing, sparky, tree surgeons,
Why organised by stress?
We're all different and what I may find stressful may be a fun thing for you.
I know someone who, later in life became a delivery driver. Loves machines, loves driving but the stress is off the scale. Deadlines, traffic, accidents, the interconnections.
Similarly, I once had to hire a tree surgeon to top a tree. As someone terrified of heights I was intrigued by his work. A more laid-back, interesting chap would be hard to find. The amount of time he spent on the ground as opposed to the tree was very interesting. Most of the "work" was expended in planning. The execution was the easy part.
If this is something you're genuinely interested in, there is no shortage of literature out there and services to help us assess what we might be good at, what we'd enjoy and what would fit in with our priorities, new or old. It may also be no harm to consider the "holistic" view, by that I mean the totality of our lives, priorities, habits, relationships, the whole shebang. If not now, when?
There is always the possibility of a whole new direction underpinned by new education and qualification.
For the sake of transparency, I was self employed and an employer for the guts of two decades. I changed direction, retrained and started in a whole new career, in a relatively new (to me) country. It hasn't been easy but I'm thriving and regret not a thing. I tend to always have a few ideas simmering away for what I could do but I'm currently enjoying settling into a new lifestyle and don't feel any urgency to pursue them and enjoy the absence of stress and responsibility of being a boss.
