Hey there! Learning a new language is as adventurous as it is tricky. Being a learner myself (I am learning French), I am aware of the shortcomings and the challenges that a student is supposed to face during this process. And the purpose of your desire to learn the new language plays a very crucial role.
Hindi is my mother tongue, and I am sure I can be a great help to you when it comes to teaching you Hindi. I have a firm grasp over the two languages (Hindi and English) and I have been writing in the two languages for five years. It would be great to go into the details like the proficiency level you would like to have at the end of the lessons, or the time we have before us, etc. I am looking forward to hearing from you before either of us makes a decision.
Regards
