I really don't want to do this, but **** it, It'll be informative and useful for you guys. I was kinda weighing whether or not I wanted to do it, and figure nothing too terrible could happen.
I've been a professional for 17+ years and will be making it 18 on February 27. Any Sifo who's turning professional currently most likely does not know who I am. I made many friends in school as well as online playing other games, mainly Call of Duty and League of Lesbians.
I will try my best to answer your questions. My answers are based off my experience, which is not "textbook".
Ask away.
