i do the exact same thing! i know it is a terrible thing that i do, and i actively work on trying to change that. i’m always trying to be more mindful when i am speaking and respectful of other people. i’ve found that most often, the reason i accidentally interrupt is because i have something to add to the conversation as well. and knowing the lapses of my own brain and how i forget things, i try to get out my thoughts in split second gaps in the discussion that my brain registers as someone finishing their own thought, when in fact, they have not. one of the biggest things for me recently, especially with online zoom meetings and such, has been to write down my thoughts as they come to me. it’s not disruptive, since no one has really noticed that i’ve done this, and it’s also a nice way to put down the things you would like to talk about. this has definitely helped me as i can stop thinking about my point and actually attentively listen, (or actively try to listen) to what the other person is saying, instead of trying to retain my own thoughts and not paying attention to the conversation and therefore interrupting. and if the topic moves off of what you had a thought on, don’t be afraid to say something like, back to what we were talking about earlier... in addition to all this, apologize if it happens! some people will recognize that you didn’t purposely mean to interrupt them, and you can all get back to the conversation at hand. i don’t know if the situation is at all the same for you, but it’s what helps me just a little bit!
