When you see people who have been to wars, you can easily identify them. Some have the scars to prove it; others have one arm cut off, etc. This does not teach that you should be a cripple to prove your success. Rather, it tells that you must dare to face the future by taking strategic risks and opportunities that are likely to come with marks.
The mark reminds you of your courage to face the battle head-on.
Some people look so clean and neat because the never take actions. The fact that those who played the game are sweating and dirty all over means they entered the tournament of risks to score better goals in life!
Think about this; "are you so neat in your clean gown" or "are you sweating in your dirty jersey"?
Do something, make the mark, take the risk, dare to win and why not???
