I don't like how I comunicate

I really hate the way, I'm talking, I'm writing and so on, however this may be my underestimation of well... me... But really comparing actual my writing and speaking (communication skills), and skills that I'm capable in possessing now I'm really Atila The Hun.
This kind of thinking on one hand helps to try to improve, on the other this lead to low self confidence, which is not exactly the property you'd expect from decent speaker - writer.
So what to do? Theory and practices the first thing, that pops in to my head every time, I think o learning of any kind. OK, now let's be more specific. What books and what kind of training? Yes, books, because, thats the best source of knowledge, at least most accessible one. So I came across with a book called "Thank you for arguing" and going to stick with that book until further notice.
However any good theory is useless without good practice. Where to practice? Now that's the question.

Whats new

No news - good news right? May be not, because, nothing new is nothing better and in my life philosophy there is no "good", only better. This is called habituation and it goes like this: if you fell better because you improved something you'll fell better for awhile, but soon get used to this, and this will stop making you feel happy.
My point is this: happiness is in changes, it's not some permanent state. That makes sense, because it's evolutionary advantage. It's good thing to fell euphoric, if you achieve something, not so good staying in that state permanently, because there would be no reason to achieve next thing. Right?

P.S. I know, that usually (like right now) I am being banal and have clumsy language, but... well don't like it, don't read it.
