Victorious warriors win first and then go to war, while defeated warriors go to war first and then seek to win.
Sun Tzu, The Art of War
Fighting and hunting are forms of competition as the application of skills will determine success or failure. Getting into any competition without previously having tested skills and trying to win puts you at a severe disadvantage.
Developing a winning mindset requires attempting to win. Go find something challenging to participate in and do your best to win.
