Please check my grammar

I, honestly, chose this course not because I like this I just found myself putting BS accountancy as my first choice. I'd never imagined myself being in this major. I really want BS business administration because I am interested in business matters since I was little. Considering that fact, it had been easy for me to like my course and be committed in this major. I may not have good reason why I chose this course but I am sure of myself that I would do my best to achieve my goal and be a successful CPA.
In the next five years, I'm planning to engage in public practice and exercise my license, of course I have to take the board examination first. When I have enough savings I will put up my own business. Therein, I will work as manager and accountant as well.
