A Psalm of Life: This poem is known for its optimism and the theme-right attitude of life. The poet gives out the message that pleasure or sorrow is not the goal of life. The purpose of life is to carry out all duties and responsibilities for the progress and good of all. We should realize life is shorter and quicker. Life is like a battle field and we should not let ourselves be driven like cattle. We should fight bravely as heroes. The poet points out that the past and future are of no significance. We should concentrate in making the best out of the present. We may also follow footsteps of great men who had laid their footsteps on sands of time.
