Polish: What did I miss?

I’ve been living in Poland for many years and I’ve never really learn t the language but as of next week that will change as I’ve finally enrolled on a course. I will study 2 times a week and I hope I can benefit from it by finally speaking fluent Polish.

I will dedicate time to learning what they teach me by committing a couple hours a day learning Polish and it will be interesting to see my progression which will develop a little at a time. If I learn it will I use it more than I use English?

I believe that until we try we don’t know the answer.
