Try to be a little bit more spontaneous in every way you can imagine even in your every day life. Not only in speaking. Try to remove any expectations as much as possible - let the reality surprise you. This is real spontaneity. - I know this is sounds short but it takes time to develop such habits (and its simple just like trying, how can we make habbits and learn new things if we don't try and make mistakes, children learn fast because they make mistakes, and they don't care about that until some adults tell them it's not ok to do mistakes ... and what is a mistake ? - it doesn't matter, it makes you learn faster, it makes you see all the possibilities for action, it makes you smarter) What do you exactly do to improve your speaking? Much understanding and support here ! <3
