I was also this kind of person. But just that i am an ambivert. I love talking alot and it lead to me spill out some certain things that are better left unsaid. They were even times where I told some of my friends about my personal life and they used it against me when we had an altercation. So I have just learnt to watch what I say and watch the kind of person I say some certain things to. I am glad you were able to stay away from such habit , because it is actually very bad.
