Mind what you say

Critics call it, the degradation of modern language. Our conversation is often full of phrases such as like, you know, but, actually to mention a few. Its a fairly common habit and most people are aware of how dumb and unconvincing these methods of conversations are. One needs to consciously change this habit. Personally I have recently acquired the habit of saying cyou know at the end of half conveyed sentences and although the person standing in front of me nods vigorously, I know they dont know. So what do I do to get rid of these annoying habits, I read a lot and watch movies and television series (like Downton Abbey) thatll help me increase my vocabulary.
