The competitor in many ways is time. (Brad Feld, writer and speaker)

Unlike baseball, where the end of the ninth inning in a crucial game can go on forever, other games are really time sensitive. The last minutes of a football, soccer, or basketball game can be nerve-wracking. In those sports, you have to beat the time clock to win the game. It’s that way in school or business life, too. Deadlines are a part of life. So, it’s extremely important to guard and invest our time well.

Remind me that my days are numbered—how fleeting my life is. (Psalm 39:4)
Those who are wise will find a time and a way to do what is right. (Ecclesiastes 8:5)
