These are mine. Note I am very new at this, it's been a long time since I studied a language, and my entire exposure and motivation to Thai is getting hooked on their dramas. So my focus is on hearing rather than speaking.

OST with Romanized lyrics (syllables written in Latin characters). Turn earworms into study ;P  This has greatly helped my ability to differentiate sounds, like increasing the resolution of an image.

Using actors' names as vocabulary and opening credits as flashcards for learning letters. This has been useful for remembering letters which are distinct in Thai but not so much in English as I can associate each with different actors. For letters I'm using Write It! Thai and Thai Script, they each have different strengths. Thai Alphabet Charts app is an easy way to look up letters when I'm confused between similar ones.

Thai Lessons by New https://www.youtube.com/@thailessonsbynew has been good for learning more when I have questions about words I'm now catching in drama dialogue.

Thank you for your list. I will use it as incentive to take my learning further.

awesome! I think you're already doing everything right, the most important thing is to have fun while learning, otherwise you won't stick with it. Thai is very rewarding to learn, especially when you're already hooked on dramas. grammar is a breeze and once you have the script and the tones down, you're sailing!

Thanks for your encouragement :) I'm hoping I'll improve with discerning tones soon. I don't know if I'll ever be able to hold all of the letter info in my head though. I've been able to translate (with dictionaries) from four languages over the years (ancient Greek, Hebrew, French and Scots Gaelic) and am still comfortable with three different alphabets but those wee loops in Thai are a struggle :D

that is certainly true, but the Thai script is also very pretty! at least I think so. so, for me it's really fun to just copy down texts in handwriting, it's like drawing at first and before you know it you get intimately familiar with the letters. bonus, if you actually know what you're writing, of course, because then you can read along and work on your spelling at the same time.

I can very highly recommend the book "Read Thai in 10 Days" by Arthit Juyaso (Bingo Lingo), it's especially good in teaching you how the tones work exactly.

and for reading and writing: "The Story of Palm" by Palm Samran, it's a comic book in Thai script that also comes with an English translation, glossary and word usage, quizzes and games to help you learn and downloadable audio files of the author reading the whole thing to you, so you know what it should sound like. the author also has a bunch of short stories on her website that do similar things and are completely free: https://palmsamran.com
