let's discuss......speaking skill problem

[spy4me]

hi everybody, today i come with a new topic which i think it's very important for both student of english and people as simple learners, it's one of the four english skills; speaking
speaking is the most important skill in communication, and if you can't speak right you can't convey your messages well
perhaps all we have this problem, we don't have the ability to speak fluently or at least correctly
do you have this problem? what are the obstacles that face us to not speak as a native speaker? and how we can improve speaking skill
?
your opinions are most needed
