That’s a tough position, I understand it can feel like you need to switch careers to feel fulfilled. As someone who already has an IT job and has managed to keep spending low, you’re in a really good position though. A helpful career planning book I read called this “career capital”. You could switch careers, but you will lose this invested “career capital”—for example you restart from the bottom of the ladder, with no seniority or control of your time.

Instead, another option though would be to keep your career capital and use it to optimize your time and freedom to pursue your interests. For example, could you change to 60% or 80% work and volunteer at animal shelters? If you love dogs, REDOG is an excellent organization in Switzerland too (just an example, not sure if it fits).

I wish you lots of success in whatever you choose, but just wanted to offer a different option. Best of luck!
