Well, I can't offer any advice, but in the spirit of 'Hi, my name is BadMojo and I'm a career changer...' I'll add my two pence worth.
You only have to google terms like, 'career change too many choices' and you'll find dozens of self-help, motivational articles on the position I find myself in. Despite reading several of them, I still feel lost.
I have lots of interests and think about how I could turn them into a career (doing something I enjoy), but I tend to overthink things and try to plan them to the nth degree to a fully fledged career - it doesn't work like that (for most of us).
One thing I did take away from my reading is that there comes a time when you just have to go for it and see what happens. If it doesn't work, then adjust and try again. But putting it into practice is another matter entirely.
I've been a Coastguard for 15 years and it wasn't a career I pursued. I sort of fell into it as something that might be interesting. I loved it. But the powers that be decided to save a couple of quid and for illogical & political reasons, my station was closed last week.
I've been trawling the job sites looking for inspiration, but I'm going nowhere fast. Like you, I've also considered getting a trade, but the problem is time. Trades like electrician, plumber, require experience and getting that at 40+ is very difficult. My cousin is 10 years my junior and couldn't make his dreams of becoming an electrician happen, despite spending thousands on training. The money is in the training courses and providers will tell you anything to get their hands on your money. So unless you have contacts in a trade that can take you on, it'll be very, very hard.
I need to get myself a job by the 13th February so I don't have to suffer the slings and arrows of signing on.
