> I know multiple people that have changed employers every couple years throughout their thirties. Each time it was a better deal.

I actually myself did exactly that -- my _average_ stay at one place is under 4-5 years, all over 35+ years employment history. And a better deal it was, in some way anyway. But it still hindered my evolution, and secondly, let us not forget that the OP seems to be based in EU, finding a good-match employer might be harder next time.

This is why I didn't recommend it.
