One single second makes all the difference in life.
One single second... when you lose all your strength. One single second... when you make the final choice of quitting or trying again harder. One single second... when you make that one wrong or right decision which holds the power to change your life; which decides how others are going to look at you and how you are going to look at yourself. One single second of weakness... holds the power of splashing water on your years-long efforts, no matter how long you kept yourself strong.
Life is a game - a game of "one single second" and it's not how well you played during the whole game that counts; it's how well you played that "one single second" which makes the difference.
