>>4Pretending to vlog can help, but it's more or less one-way communication. There is little interaction between the audience and the vlogger. I guess it'd help in collecting thoughts, but I think it fails in "connecting" with people. When I say talking to myself, it's more like I'm talking to a different person with similar likes, to discuss whatever idea I have in mind. Like how I'd tell "myself" how morally wrong it is to love Belial from GBF, but "myself" would justify that since it's fiction, it's fine. Or like I'd make a persona based on whoever character I felt like talking to and create a dialogue with me and them. Something like that. This actually helped me polish my spoken English throughout the years, but I started doing this in my mother tongue.
I never read books written in my mother tongue (unless required in school), but I did listen to the people around me while they talk, whether it was casual or serious. Then I pretend to act like those people and carry on a one-man performance in private. Yeah, I know it's bad to eavesdrop lol but I was a kid when I did this so it was fine. If watching and acting like the people around you feels VERY difficult, try re-enacting some drama scenes. It's not as awkward as copying the people you know.
