MMA career

hey guys, I am really loving MMA more and more each day and I would like to fight amature then professionally ( UFC ). and also complete my university studies but my question is to people who have had some amature, professional fights and coaches of fighters and any mma experts.



what is the key factors to becoming a great MMA fighter? for example what makes jon jones, George st pierre, Anderson silva and other successful fighters so good at MMA and others like Jason miller, josh koscheck and chris leben an ok fighters and other fighters really bad.



thanks
