What does the word momentum mean to you? I'm sure a lot of people would have different answers to this with vast differences. A scientific explanation of the word "momentum" for example, would be a heavy truck moving rapidly has a large momentum—it takes a large or prolonged force to get the truck up to this speed, and it takes a large or prolonged force to bring it to a stop afterwards. If the truck were lighter, or moving more slowly, then it would have less momentum. Well that's the scientific explanation as I said, but what is the life explanation for this? Or rather YOUR own explanation? For me momentum means giving nothing less than a 100% to everything you do in life, paying attention and doing all tasks with details, always be driven with determination and working so 'HARD' at whatever obstacle you have to complete that at the end of it you will look back at it and go like, "wow, I really gave it my all" with a smile on your face. I believe if we apply the 'just do it' equation to whatever task you want to do in life, then there is no possible way you can ever fail. The problem with most people is that, when they start off with something and fail one time, they throw in the towel. When they should actually do the opposite and pick the towel up and try twice as harder. We as humans are more afraid of the though of failure then we want than the possibilities of success. If one can channel out negative thoughts and have momentum in whatever it is your doing in life, then trust me.. You will be a happier and more satisfied being than anybody else.
