My Learning Experience in Thai

Hi I'm native Thaispeaker. You've written well. I understand the effort it takes to learn a new language, especially the one differs so much from your own. I also know the difficulty with "ร" pronunciation. You don't actually have to worry about ร because the ร sound is in most circumstances omitted. Simply pronounce it ล if you can't do the thrill. Don't give up.

Here's my corrections on your note. Hope this helps.

Firstly: ฉันมี่ชื่อไทยค่ะ นี่บัวค่ะ In general "นี่" could be directly translated to "this/that(pronoun)". However, we don't use the word to introduce our own name. You can safely say that นี่เพื่อนฉัน ชื่อบัว or นี่บัว เพื่อนของฉัน, but for our own name we use ฉันมีชื่อไทยค่ะ ฉันชื่อบัว หรือ คือบัว instead.

Secondly: For บัวอยากรู้จักประเทศไทย ขึ้น I understand that you want to get to know more about the country. More, in this sense, is equal to มากขึ้น (and the opposite is น้อยลง) It's a kind of tight binding of two words that always go together.

Thirdly: There are also some typos and miss arrangements in sentence structure.

Lastly: บัวต้องทำอะไร could be replaced by บัวควรทำอย่างไร which is smoother and more politer (You can think it like when you use would instead of will or could instead of can)

Overall this is very well written. Again, don't lose your passion. Thai language is doorway to our culture. If you have questions about any specific point, simply ask in the post.

The sentences I edited above are easy language. It is not formal but we can understand if you can speak as good as you can write.
