I've researched this a lot and have thought about doing it on off for a couple of years and know some people have done it.
There basically two ways to approach one is with a certificate the other is without. Having your TEFL/TESOL cert. doesn't guarantee or even better your chance but if you have never taught a class or any kind especially a language one it helps. There are tons of places that do the TELF/TESOL cert online and in schools my college campus for example has a institute which comes and does the course about 4 times a year and its expensive runs you almost $1,300 for a 8 week course, online you can find courses for way cheaper but 99% aren't worth shyt and don't replace a classroom experience so i recommend if your going to get a cert. do it in a class room setting. I went to one of there information seminars and as you would expect there setting you up to be a English teacher in 8 weeks. The course itself seemed intensive but it was set up in way that no one would fail. You also get to keep all the learning material and they help place you, although something about there placement catalog didn't seem right, because i saw a few countries in there that were not listed as needing TELF/TESOL instructors when i know they did. If your going to get a cert, again classroom is the best way.
Yeah, I was gonna take one of the in-class courses. I feel that the online thing would be a waste, since you get no real classroom experience of any kind. Also, depending on what school I finish my degree in, I want to major in English Ed. or ESL...
Now the second way to go about this and i know 2 or 3 people that did it this way is to do the job research yourself, and go travel/move to said country and find your self a teaching job without a certificate, this again is tricky if you have never taught, i have taught pretty much all ages from small children to older adults , never for a extended period but enough where am slightly familiar with lesson planning and other classroom procedures etc , even with my semi experience i would not go about this way i only learned after i sat in that informational seminar and was browsing through the course text books. Teaching is not easy. Now with that said the people that i know that have gone this route have literally just packed up there bags moved to XYZ country got bullshyt part time jobs/ side hustle,tutored for cheap and looked around for teachings job until they landed one, the time ranged from a couple of months to over a year.
Shiiiii, if I had the money/resources for it I would....But then again, the countries that I want to go to want a degree of some kind.
Certificate or not one thing i can tell you from the door is that no matter where you go the pay is not all that , yea will you probably make a bit more than the locals but nothing fabulous, that may or may not be a issue depending on how you look at, remember the average cost of living outside of the U.S is relatively low. Your salary which from my research most countries outside of here pay purely on salary not hourly and even more pay monthly salary which means 1 paycheck a month , this salary will also depend on how many hours you work , some places might have you come in a do one class a day, other places will have you do 3-4 classes which if your not prepared can be overwhelming as fuk, but then again having a lot of work is a good thing , something you can do to supplement your salary which is really popular and the route i would personally like to take before i ever entered teaching full time is to tutor.
Teaching English as tutor has its benefits and pitfalls from what I have been told. Benefits are its a great way to make side money when your not getting enough hours teaching, its a slower paced environment since your usually one on one with a student so its less pressure on you if you are not comfortable teaching 10+ people at a time, so in the sense of doing it to get extra money tutoring is great. Now tutoring as living is tricky i know two people who have done and are on opposite ends, one person say its horrible , reason being because starting off there is no consistency , you could start off with 5 students and by the end of the week have 1 student or no students, also because your doing it all alone you have to be very organized as far as scheduling and preparing materials goes. The other person i know does tutoring exclusively they admitted it took them a while to get a constant group of clients but once they had it up and running the money came in steady, that's the other benefit of being a tutor full you get to dictate for the most part the price, place and hours.
I think that should give you an idea on what the learning/ teaching aspect is like
Cool. I know I won't necessarily get rich, but the money is probably good enough for a single male with no kids or wife. I don't mind doing some tutoring on the side if needed, as well.
Other things you need to consider are
-Countries you want to teach
- the moving process
- visas rules
-work permit rules
-immigration rules
True. I think the only places I may have a problem with are in the Middle East, but that's if I even wind up going over there at all.
It's been an hour already.
Thats like a deal breaker for me. I would like to try other cultures foods but I also need the option of making my own. She said she basically ate some type of frozen dinner shyt EVERY NIGHT she was there because she didnt "trust" the food. Thats her fault though. 
When she left she said she cried again because she really enjoyed herself plus i think after that year she walked away with about 12-15k because most of her living cost were paid. She is dying to go back lol
She said it was nothing to see a drunk china man at 10am
