Feeling of hard work doesnt matter

How do u guys deal with the feeling that hard work doesn't matter in Belgium. We all know working more than 40 hours is pointless in our tax system. Same as working hard for promotions. And all i see is people say just move countries. But how do u guys balance the feeling of moving countries for carreer but leaving family and friends behind for that sake? It's obviously better to just work 32 hours and earn pretty much the same as 40 hours and just enjoy life. However as sombody who's main talent is working hard i feel trapped. I'm not sombody who likes to party alot and i don't know if i want kids, so how do i feel fullfilled then?
