As one matures, you begin to realise decision making, both the speed of it and the consistency of selecting the right decisions is arguably the greatest determinant of whether or not you make it into the professional game. It explains why the likes of Iniesta, despite their physical frailties are nigh on untouchable as mere mortals simply cannot compute at the same speed. Trying to induce errors from such players is very difficult as they have developed ethereal game intelligence. The sooner you can improve your decision making, the more drastic your increase in value on the pitch.
