Your mental attitude can not only shape your entire game, but the way that you view yourself as an athlete. Negativity also tends to accumulate.  When negative thoughts go unchecked, they can snowball, growing bigger and leading to more negative thoughts and an overall pessimistic attitude. When this happens, it can cast a shadow over everything- from the way you perform under pressure, to your relationships with your teammates and coaches, to the way, amount, and frequency that you practice.

Fortunately, with the right tools, you can break out of the cycle of negative thoughts and give yourself a more optimistic outlook.
