I don't sacrifice anything but without BJJ I think my life would be much poorer.
I personally would not take a lower paid job just to be nearer to a BJJ gym, but then I have a family to support. Can you afford for an instructor to visit you and give privates? Can you start an informal grappling club with a group of guys. Is there judo or MMA nearby? What if you travelled to train at weekends, then take various odd days off during the week to do a private? I think there are other options less drastic than quitting your better paying job. No?
