Unlike many European countries, Thailand is not interested in welcoming dead-beat foreigners, (unless they are rich, dead-beat foreigners). The employment laws of Thailand protect Thai people from foreigners who want to 'muscle in' on their low-paid, basic jobs. Do not even think of working in these types of jobs because immigration will rapidly catch up with you!!
However, it's always good to be optimistic/glass half-full 🙂 You don't have a degree. But what is your nationality/native language? If it is not English (and I'm guessing that you are maybe Italian - apologies if I'm wrong), then you may be able to earn a reasonable income teaching your native language 'online' through a website such as Italki. That website lists 2 kinds of teachers >> Professional teachers with degrees and relevant teaching experience, and Community teachers, who don't have degrees, and therefore charge lessons at a lower rate.
If you want to teach English online, I'd say no chance!! (too many people doing that already). But if your native language is not English, then you stand a chance of getting paying students, no matter how obscure your native language is!
The legality of teaching online in Thailand is a bit of a grey area, but if you only teach non-Thais, then you should have no problems.
I'd guess that a Community teacher of say Spanish or Italian on iTalki would earn about $10 USD (tax-free) per hour.
I used to teach Science-in-English via Italki, and I was inundated with students (because of my Science knowledge). I recently stopped teaching via iTalki after having earned $100,000 USD (that took a few years!)
Check out the Italki website. I think it's the most realistic option for you.
