Should I try to go for jiu-jitsu coach or just stay as a personal trainer in gym?

Today my coach surprised me with a promotion to black belt. I didn't expect and it made me very happy. He even told me that if I get some dans i might become a coach in his dojo. Im really thinking about it. I make good money as a personal trainer (in dojo i would probably make less) but it kinda drags me that way since i love jiu-jitsu.
