If your single or spouse is supportive do whatever you want. Money is not everything so if you have to take a cut to do something you like, tighten the belt and enjoy your life.
I did a career change because I was basically a robot with better dexterity doing the same 7 tasks every day. It was hard at first and I had to bounce back to Mom's for a year but now I am quite successful and I LOVE my job.
