You're right. English is not my native language, and I learned it in the school, which included speaking, albeit not too much.

The steps I outlined is how I sharpened my skills after school, during my non-educational life, in a spontaneous manner. I understood these steps years later, and share them whenever there's a chance to share.

I've practiced my speaking skills in the university via presentations, and during my work travels. Also my work requires me to send a lot of English mails, which tend to progress conversation-like. Since they were the things which came to my way rather than I consciously selected, I have no reproducible way of practicing spoken English, so I knowingly omitted those.
