If you have to run then learn from Bolt, if you have to fight watch Muhammad Ali`s jab and grab punches, if dunking with a basketball does it for you why not pull a Vince Carter or fly in like Michael Jordan , if science and evolution tickles your fancy have you read "Evolution" by Charles Darwin? Well, Like Martin Luther king said " If a man is called to be a street sweeper, he should sweep streets even as Michelangelo painted, or Beethoven composed music, or Shakespeare wrote poetry. He should sweep streets so well that all the hosts of heaven and earth will pause to say, here lived a great street sweeper who did his job well." So pickup that broom , get started and stop complaining!
