Yes you should do it! I just done my BS module training in Oct, was lots of fun & hard work, but trust me, it’s worth it. I never torch before & certainly get nervous in the crowd, its all come with lots of practice, eg. Listen the tracks in the car & practice & talk; one instructor said to me, "you've got the move just need to learn “how to talk”, I started to shadow on the stage with other instructors, it feel great on the stage, tonight will be my 1st time teach a track in the class! So looking forward to it.
I work full time as well, but don’t think too much, get the training done first and see what lead you to. Go steppers go go….
