Sport Psychology

Success in sport is not a matter of chance. It involves a conscious effort requiring both knowledge and commitment.Likewise, achievement in soccer is not entirely physical,technical, or tactical. It is also mental, and offen more mental than anything else. To say that athletics is predominately a mental game is one thing (sometimes surpassing 75% in importance), but to really understand it is something else. All coaches and players agree on this. But they typically just say things like,"have a positive attitude", "focus", "Have some heart", "Stay Relax" etc. Beyond that, little attention is devoted to the subject. And that's mainly because the vital relationship between the mind and body has not been fully appreciated or understood.
The attitudes and habits of an athlete will be ultimately determine how successfully they face the challenges of today's event. Today top soccer players realize that unless they are constantly changing for the better (Continuously Improving), they are changing for the worse.
As Players mature and progress with their skill they will notice that life's challenges are still there.When it is not possible to control the events in their lives, they can still control their responses. All athletes are responsible for their actions and decisions. Life's challenges don't control them; they control themselves.
The events in their life may not be "good" or "Bad" . Sometimes it may be simply be a matter of perspective.
