I am looking to do another ESL/TESOL course and I was wondering what you would recommend.
I recieved my Teaching Certification in the United States (though I am Canadian), and I have already taught English for 7 months in Korea (my co-teachers are very happy with my performance but I would still like to continue to improve as a teacher).
I was planning on doing a Celta or eqivalent TESOL course in order to become a better teacher, while also opening up doors to better job opportunities.

What courses do you recommend I take?
Any personal experiences are greatly appreciated!
