[00:00] Common mistakes sports bettors tend to make number four. Overconfidence and a lack of re-evaluation of your strategies. And I was very guilty of this after a month or so of betting. So after a month, I had made about $1,000 in profit.

[00:14] I felt I knew everything. I know exactly what I'm doing. And then I thought this strategy I'm trying is just perfect. It's so good. There's no way I can lose. It's definitely profitable. And then it was keep betting on it, keep betting on it, keep betting on it. Until eventually a couple weeks later, I realized I've just lost $400 in a day.

[00:29] And then recently I have been on a bit of a decline. I wasn't really working out the expected values mathematically anymore. I was just going with what I felt was right. And I was basically doing this because I had made money early on

[00:41] and I was very confident in what I was doing. Way too confident was the problem. Eventually I got to a day where I lost over $1,000 and that was when I realized, okay, I probably want to work out how profitable these strategies are.

[00:53] Once again, mathematically.
