Perpetual optimism is a force multiplier.
— Colin Powell

Have you ever needed to get a long, stubborn nail out of a piece of wood? Sometimes you can extract it using your hand. Other times you need something stronger. Enter the force multiplier known as the crowbar. If you take a crowbar to any unyielding nail, it will, without a doubt, pop out. A force multiplier, as the example illustrates, is anything that drastically increases your effectiveness. This could be a tool, tactic or technique. It could even be a temperament. 

Optimism, as Colin Powell suggests, can act like a force multiplier. Continually filling your heart & mind with it has a way of producing the kind of outcomes we all hope and wish for.

Take some time and think about the force multipliers in your life. List them out in your journal. If you're having a hard time thinking of some, ask yourself: "What action, thought, or thing dramatically increases my effectiveness?"
