What stops you from winning and performing at your best? Your ego. Your ego ensures you get in the way of yourself when you're doing something important: whether you're preparing for school exams, taking your driving test, playing a sport, speaking in public or making a business presentation. Whatever you do, your ego is sure to interfere with your performance. We all have egos: it's our natural defence system which is triggered when we experience strong emotions, such as anxiety and fear.
