I have no idea if its possible to teach someone how to become a profitable bettor, but I do think you can offer people some frame work on how to become better bettors. So in lieu of nothing here is a thread of advice I believe could help people to build that frame work: The biggest thing: Stop talking and listen

People are so quick to speak but if youre trying to become better its in your best interest to shut up and listen to people who know what theyre talking about.
