As a goalkeeper, the margin for error is small.
One mistake, one misstep, one wrong decision leads to a goal for the opponent. Naturally, mistakes are inevitable and nobody in this world is perfect.
The key to being a successful goalkeeper is the same as being successful in life – accepting what has happened but moving forward in a positive way. The worst thing I can do after a mistake is dwell in that moment and sulk about my imperfection. The best thing I can do is forget about the mistake and remember the number of times I have done things right, the amount of training I have done to get me to where I am, and the amount of people that support me in good times and bad.
