Vocabulary Building

I feel uncomfortable to my poor vocabulary in English. I thought only I had to do was to guess the meanings when I met unfamiliar words. I didn't have any problems at first, but now I understand how important vocabulary building is. Because of lack of vocabulary, I can't understand exact information in English articles and books so often. 

To expand my vocabulary, I'll use knowledge of roots, prefixes and suffixes. It a never ending journey but I believe it worth to do.
