34 is not old when you consider that you could still have 30+ years of working life ahead of you. Better to find a job you like to do for the majority of that (with inflationary beating pay rises) else it will be a tough road ahead
That's exactly what I was going to say. Even if it takes 5 years (which I doubt it would) to make the target salary in a new area that will still leave 25+ years of working in it...
