Everyone is capable of achieving greatness. Bruce Lee demonstrates that applying limits to oneself even on something minor can lead to a life full of limits. Life does has its plateaus that can be seemingly impossible to pass sometimes. However, once a plateau is surpassed it will always be followed by a period of exponential growth. The great people of the world have realized that plateaus are only a temporary obstacle. Even though you may not always be able to see the top of the plateau, the top does exist. Once a person realizes limits are only a mental block they can achieve maximum potential and become an expert.
