test betting with your eyes closed, without thinking about anything, without analyzing the games of the two teams, after you bet on the game ask someone to analyze the game and make a bet and when the game is over you will see the result and ask yourself: why did you bet in this game? did you make a bet relying on luck? so make more bets on the remaining games always with your eyes closed so that you don't analyze the games, just count on luck and after 10 games see how many games you managed to hit
after that do another test making bets but always analyzing the games, you will analyze the performance of the last 5 games of each team, injured players, performance of each team away or at home, the probable starting 11 players, the value of the odds and then do bets on at least 10 games that you will see that you will have better results than betting on luck, because in sports betting there is no luck, there is only strategy and knowledge
