There's a way.

My friends visit me twice a month, and we study English together. Before reading a textbook, we always have an hour or so speaking English. It's hard for me to express my feelings or talk about my experiences in English, but I try doing my best.
I make it a rule not to use my dictionary when I'm writing or speaking, because I tend to rely on it too much. Checking dictionaries would be better way to have a large vocabulary, but it takes some time and makes me irritated.
"Make it simple."
One of my friends, a guy from Canada, replied like this when I asked him how I could make myself understood in English. Now, I seem to understand what he meant.
