Motivation is what drives you into achieving goals in life. Without it,any task you will perform will feel dry and empty. It is one of the core differences between a hard working person and a hard working machine. Also, motivation acts like a sort of adrenaline rush in the blood stream. It can make you achieve things which you normallycannot. It is like the fuel that keeps a fire burning. But like any fuel, motivation can also run out. Sometimes, it can just get dry on its own. This is especially true if the goals being pursued still appear so far away. That is why motivation is something that needs to be renewed from time to time just as you would refuel a car once its fuel tank is empty.
