I also practice BJJ but think of MMA as a pretty brutal no holds barred sport. The 2 things are not the same (although often talked about as being the same). BJJ is a (relatively) narrowly defined practice. MMA is a sport where you can bring any fighting practice or combination into the ring (and the successful fighters bring many). BJJ is a big part of MMA, but arguably no longer the defining skill needed to succeed (especially in the past 5 years or so).
