It all started around the time I got to university to study Math.I think there are two reasons to that. Firstly some subject forced me to think more visually which was not natural to me. Secondly i started reading more books in english which is not my first language. Now here is my problem. In the past I was able to formulate in my head long train of though, strategies and stuff normal people do [in my first language], now all I have in my head even when I focus are some images and gibberish words in english. How can i go back?
