•  Our life is just like a chemical reaction of chemistry means minimum two reactants are required to make a product. Here the two reactants are, the first one is myself and the second one is condition or situation of our life both together we call it present. The way how we approach the situation is called as reaction mechanism. The product we get in the reaction we call it as future. And after the completion of reaction we call it as past. So its important to give emphasis on the present to make our future bright and feel proud on our past.
