On the best sunny day, the most powerful magnifying glass will not light paper if you keep moving the glass. But if you focus and hold it, the paper will light up. That is the power of concentration.
A man was traveling and stopped at an intersection. He asked an elderly man, "Where does this road take me?" The elderly person asked, "Where do you want to go?" The man replied, "I don't know." The elderly person said, "Then take any road. What difference does it make?"
How true. When we don't know where we are going, any road will take us there. Suppose you have all the football eleven players, enthusiastically ready to play the game, all charged up, and then someone took the goal post away. What would happen to the game? There is nothing left. How do you keep score? How do you know you have arrived?
Enthusiasm without direction is like wildfire and leads to frustration. Goals give a sense of direction. Would you sit in a train or a plane without knowing where it was going? The obvious answer is no. Then do not go through life without having any goals?
