Sabaide Rue Krop

Today has been a good day. I am learning to be productive somewhat as I wait for school to start again. I started my hobbies of learning Thai and Yoga again. Practicing Yoga has a nice feeling, for you are aligning your mind and body well.
When learning Thai today, I began by running with an idea that I had. A couple days ago I asked my mother is Thai a language that I can learn alone by learning the alphabet, words, grammar, reading, writing, listening, and speaking on your own. She affirmed yes as I think of the crazy Chinese language, where it is nearly impossible alone with a dictionary and a book. I tried. The dictionary had so many different meanings for one character. A simpler dictionary is required.
In the Thai language, the first ten standard letters or consonants are as follows: I don't understand how now all of them are on my Thai Keyboard. My mom is in for an inquiry.

gau gai ก
kau kai ข
kau kuad​ (letter not on my keyboard)
kau kwaai ค
kau kon (letter not on my keyboard)​
kau ra-kang ฆ
ngau ngoo ง
jau jaan จ
shau shing ฆ
shau shaang ช

I plan to learn ten each day. There are 44 consonants. I am using an app called Korkai to learn the pronunciations and tones.

P.S. I asked mom about the kau kon and kau kuad. At first she thought that the letters should be in the keyboard, but after investigation we found that the consonants are not used in the language. I can't explain it at this time because I have no knowledge why these letters are not used.
