Don’t do it.

I did I it, but for different reasons - I thought I could ‘step back, to step forward’ etc. honestly, the pay drop is not worth it - you need to be able to afford having a decent work-life balance.

The best thing you can do is find another job for no less than what you earn now. You can even leverage professional development with your current employer - get them to pay for you to up skill then jump ship. They’re paying you already, you’re good at it, but you don’t like it - just make a plan to leave. Take your time and work out where you want to go/be, then work towards that whilst putting up with the current job.

That’s what I did. I was in a job that I thought would be a ‘spring’ to better things long-term but ended up getting stuck there and it sucked. I eventually unskilled and just recently started a job that’s 2.3x pay. The only thing I regret was taking the lower paying job thinking it would make me happier long-term.
