The short answer is 'yes'. A longer one would be 'definitely'. The hesitant answer would be how well do you teach, how much do you love helping others, and how interested are you in English? I can't tell you the number of young teachers I've come across with with TEFOL, TESL, EFL, Cambridge qualifications and teaching certificates etc. etc. that are grammar smart and life dumb. In most cases, the best teachers have all had experience in plenty other areas of life other than studying. Good luck and best wishes.
