correction of my "introduction"

Hey, how's it going? I'm Richard and I live in the State Baden-Wuerttemberg, which is located in the South of Germany. Currently, I'm a student who learns foreign languages as well. (here do you mean student of some specialty ex:biology that is learning languages as well?)
I love learning new languages and that's why I wanna (you say it wanna but shall write it want to) help others to learn my native language German. Besides of German I speak English, a bit of Russian and a bit of Spanish. I had the opportunity to teach private several people the German language (to  privately teach German language to several people). These includes Spanish-speaking, Russian-speaking and Arabic-speaking people.

My focus is the colloquial language, vocabulary, pronounciation, phrases and idioms. Furthermore, I'm gonna (going to, "although you pronounce it gonna:-)    explain to you (or teach you) complicated grammar rules in an easy way (with examples), so you can understand it. And I'm gonna (going to ) show you the real spoken German which is used in daily conversations.
Please let me know if you have any further questions. I will answer them all :)
