How Can I Improve My Fluency In Spanish?

I have been taking Spanish for 5 1/2 years. My reading and writing techniques are average. However, my speaking and comprehension in Spanish still needs work!!! I have tried to ask my parents (who are of Haitian) for advice for advice by telling me how quickly they learned to speak English and what techniques did they used. They told me just to keep practicing. However, it is almost 6 years now since I have been studying the language and I still do not see any improvements. Does anyone have any tips for me so that I can improve my fluency in Spanish?
