I don't know whether my engilsh is improving or not ?

Learning foreign language is not easy as i thought. I found i could learn English just i got to any country which speaks in English. I realized that i had thought wrongly after i studied here for almost 4 months. I have to study hardly. Because some of my friends who live in native country are studying English much better than me. However I have more opportunities than them, I can't use them. I'm just lazy guy. Maybe it relates my age. kkkk. I think i need something to motivate myself to study English. I'm watching movie and reading a book. There are plenty of books free in libraries. However i like things free, i bought a book. I was interested in the book i bought because i spent money for it. I've already read seventy pages. But i'm not interested in it anymore. how should i motivate myself to study english? Sometimes i think about some people who had already reached an achievement or who have enough money and live in luxury. After that, i have full of energy to study. It might seem a little bit silly. Nevertheless i will use it until i find another one.
