How to become a professional writer

I just tiped into youtube „ how to become a professional writer“. The top three videos were of different length. I think it reflects my ambition that i didn t click on the longest one, which was itself only 12 minutes. I took the middle one, which lasted 5 minutes. I think in conclusion, i m not overly motivated but there must be someone in that position who took the 3 minute option. Poor sucker will never become a succesful writer or maybe he will. What do I know.
