Amy, I am 9-year auto adjusting veteran and I am associated with a training school (I help people get started in auto), but I would say 'No' it isn't as great as it sounds. It's hard and you have to approach a career here as building a business. If you approach this career with anything, but that mindset you will be let down.
As far as income there are adjusters who make over $100k a year, but this is not something you can achieve overnight. I have over the last 3 years personally as an adjuster made over $100k, but many years working local daily auto claims and catastrophic claims I've made $60-$80,000 and that isn't taking out for expenses.
It's a hard job, hard to get started, but do I enjoy my job? Yes, I do. I think many more people could have a successful career, but it is a massive career shift and there are NO GUARANTEES.
If you do decide to pursue it I recommend you start it as a side project/hustle that you are slowly working towards a goal instead of jumping off your current job.
