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?
I don't believe in sacrifices as a healthy way of living. It is unfair to put that much emotional investment in something ("I gave up this and that for this job/person/pet/..et.c"). It's one thing to DECIDE that you would rather work the higher paying job than practice BJJ. That's not a sacrifice. That's just living.
Having said that, I agree with Meerkatsu that there are often more options than we can immediately see. Don't worry. Be happy!

I invested in decking out my double garage with 3cm mats. I now get many extra sessions in a week. I can only get to 2 or 3 classes during the week but my mat time has increased hugely obviously.
