Any TEFLutherites aboard?

I am seriously considering doing the CELTA to be able to TEFL – I’ve got a BA in Linguistics and want to spend a good chunk of my life travelling, so it seems like a logical next step. I was wondering if any of you Jellies have any experience in this line of work and would like to perhaps share your stories, or some pointers with a prospective English teacher slash vagabond. “Thanks in advance” as we Poles like to say :-)

Cheers!
