Amazing post! First I want to say to anyone learning English... You deserve all the credit in the world because English is not an easy subject to learn! At all!!!
Second, this was my favorite part of this whole piece, "there are few things more rewarding in life than to be able to better someone else's life with knowledge". The kids that you are teaching are lucky to have someone that cares like you do!

And faking it until you make it is the name of the game in 2018! I think every successful person had to at some point in their lives!
