Potential

There was a guy was once, he was very serious about increasing his capacity of doing things.
He went to a elderly man who was good at many things.
The guy went to the old guy and said,"I want to reach my full capacity. Please teach me how to be at my best."
The old guy smiled and said, "Well there is nothing much there. You just have to train your mind and control it."
The young guy was not able to understand so he asked to explain more.
The old man replied, "I believe I can help you understand better. Do you like running?"
The young man had an amazing athelete body, he was the fastest man in town. With spark in his eyes he affirmed.
The old man smiled, there were many wrinkles on his face.
"Show me your capacity, run as much as you can right now."
Old guy was not making sense for the young one but he decided to be supportive of his old ways of teaching
He ran and ran, unless he was tired and ran until he felt very tired.
Old man was standing next to him he said, 'now it matters'. The more you can do now the better you get next time.
The young blood decided to try it once more, this time he just sat on the ground tired. His muscles were stiffer and he was tired. Sweat was drenching all over.
The old guy looked at him and said, will you like to try once more.
The young guy tried to catch his breath and said no I can't.
Old man came close to him and looked him in his eyes and said. Will you still be sitting here if I told you your house is on fire cause I can't get anybody to help you. The young guy ran right up to his house only to find everything was fine.
He went back to the old guy. His face turned red. He shouted, it's not. You lied for no reason. The old man smiled and said, but you said you can't run anymore.
The young guy understood everything. His anger flew away.
The capacity depends on our thinking, we stop where we stop in out minds.
