Aimlessness is a vice.
Until though is linked with purpose, there is no intelligent accomplishment. It is like drifting in an ocean of life.
Those who have no clear central purpose in their life fall as an easy prey to petty worry, fears, troubles self pitying. All of which are indicators of weakness which lead as expected to failure, unhappiness, loss, weakness and lack of persistence.
Whoever seeks to achieve extraordinary success or results in life must conceive in his heart a legitimate purpose and set out to accomplish it.
